70 GMC 4wd version
I have owned this truck for 11 years, bought it when i was 15 years old. I have done way to much to it to list. Small block converted to big block, 4.11 gears in the rearend, lowered it the right way after it was heated coils when i got it, so on and so forth.
I have always wanted a 4wd 67-72 and have never been really happy with the truck in 2wd configuration. Well last weekend i was browsing craigslist not looking for anything in particular when i came across a 71 4wd frame for 500 bucks. Needless to say i went and picked it up and brought her home. Plans are Strip frame either powdercoat or master series paint or chassis saver (Opinions welcome) Re-gear front axle 4.11s to match my current 2wd rear axle. Rebuild the front suspension Swap over my bbc swap in a 700r4 208 combo i have setting around Get drive shafts made 4 inch rough country lift 33 inch mickey mtz's Im sure there is alot i am missing. Pretty much i am shooting for a nice looking older truck that can still be used to pull a trailer, go to home depot and load stuff up. A truck that is taken care of but still used and not just driven on nice days. Here is a a picture of the truck as it sits http://i114.photobucket.com/albums/n...0%20GMC/tn.jpg http://i114.photobucket.com/albums/n...00704-1222.jpg Frame day i brought it home http://i114.photobucket.com/albums/n...psb4ea085c.jpg New rear tires and stuffed in the garage http://i114.photobucket.com/albums/n...ps423b9ad2.jpg Tonight when i got home i pulled the front axle, here is what it looks like currently http://i114.photobucket.com/albums/n...psda2ab035.jpg http://i114.photobucket.com/albums/n...psb188b90a.jpg http://i114.photobucket.com/albums/n...ps21544d49.jpg |

Re: 70 GMC 4wd version
Cool build, always love the four by's !

Re: 70 GMC 4wd version
Why not just find another donor truck for the body ect and sell the nice one you have already? Just think its too beautiful to tear it apart.
|
Re: 70 GMC 4wd version
Nice truck. The body swap should be easy.
My only thought was that you could change the suspension on your 2wd chassis to make it a nice handling tow vehicle, if you didn't really need the off road capabilities of 4wd. But if you're set on the 4x4 then I can't wait to see more progress! |
Re: 70 GMC 4wd version
thanks for all the kind words guys. i dont really need the capabilities of the 4wd because i have my 05 crew cab for that, however as of right now i have put 400 miles on the orange truck in the last 5 years, mainly because i dont really enjoy a lowered rig anymore. i enjoy 4wd so much more then i ever did a 2wd, so thats my reasoning on that.
also yes it would make sense to sell the orange truck and just buy a body, which this frame had untill i offered to just buy the frame not the whole truck. my reason for using the body of the orange truck is because that was my highschool truck. i have alot of great memories in that thing, now that i have two young ones i would like to make more memories in it, i am hoping it now being so low to the ground will bring the love back for the truck i once had. not to mention the orange truck was a original 4wd cab, that someone swapped to the 2wd frame well before i ever got it, so my title has always said 2wd anyhow. |
Re: 70 GMC 4wd version
See, go for it, was made to be a 4wd again. Can't wait to see the body riding high, will look cool.
|
Re: 70 GMC 4wd version
Well, guess you cant argue with the sentimental part of the reasoning. As for me i have the same sentiment with my truck, been in the family for a long time, won't ever sell it if i can help it, but i also dream of having a 2wd and at one point i thought about making it into one but decided that someday when the time is right i'll just buy another. Good luck, i'll be watching the build!

Re: 70 GMC 4wd version
In the process of stripping the frame still, i only get to work on it about an hour a night so its slow but steady.
In prep of getting things ready i have been looking for shackle bushings. For the front leafspring rear location, and the rear leafspring shackle location, pretty much the bushings that wont come with the lift springs. Does anyone know where i can get some of these? maybe in poly? thanks in advance. |
Re: 70 GMC 4wd version
Offroad design has some super nice greasable bolt kits and bushings, the bolt diameters are stepped up one size, they will need to know what springs you have because different spring Mfgr's have different eye diameters. I used them on my install.
Not sure about where to get rubber bushings except a truck vender like Classic heartbeat? |
Re: 70 GMC 4wd version
The only shackle bushings I found for the frame are Skyjacker and I bought them through Jegs item # 825-se-12c

Re: 70 GMC 4wd version
john thanks for the info.
Got one side of the axle torn down this weekend, need to finish the other side and send it off to get it regeared and new seals and bearing. http://i114.photobucket.com/albums/n...psbce7ca9f.jpg http://i114.photobucket.com/albums/n...psc3a9b1c0.jpg Started to paint the front end parts also. http://i114.photobucket.com/albums/n...ps9c84e9fb.jpg http://i114.photobucket.com/albums/n...psb1624a82.jpg http://i114.photobucket.com/albums/n...ps8f443a72.jpg |
Re: 70 GMC 4wd version
Guys i need some opinions, i am up in the air on wether to poweder coat the frame or use master series frame paint on it. I have seen members use both, just would like some good opinions.
I can get the frame powder coated and sandblasted by the same guy for 400.00 or i can get the frame sandblasted by that guy for 200.00 to 250.00 and then buy the paint for about 100.00. so the price difference is not that big, just wanted some opinions. I was originally going to strip the frame myself and then use the master series, but after working on it for about 2 hours i think it would be money well spent to pay someone to sandblast. thanks in advance. |
Re: 70 GMC 4wd version
I stripped mine by hand and in hindsight I should have had it blasted. A little cash saves lots of time and ensures all rust is gone. For me paint was better than powder coat due to the ease of touching up later as I modified the suspension, transmission, hitch receivers etc. and needed to drill new holes in the frame.
|
Re: 70 GMC 4wd version
I had mine blasted and painted, but that was before PC was so accessible and affordable.
I'm extremely happy with the pained frame. Today if I were to do another; taking the hassle factor and convenience into account, I'd do the PC since it's so quick and easy to get it done now a days. |
Re: 70 GMC 4wd version
I agree on the paint, sure some day in the future you will need or want to touch it up or modify something as mentioned.
|
Re: 70 GMC 4wd version
Sand blast then come back and hand sand with 180, then prep and paint with an epoxy paint, then top coat with chassis black. Powder paint is for show cars that never live in the real world. If you expose any metal from underneath the powder paint rust will start and spread underneath the paint. Look at any snowplow frame, trailer hitch, etc. etc. Epoxy paint is what is use in tanks at water/sewage treatment plants and chemical plant tanks and pipes etc. Best your going to use and will last longer than anything I have used. Good luck.

Re: 70 GMC 4wd version
Guys i need some help. Im pretty bummed right now the driver side front axle kick my butt the last two nights taking it apart. Every piece in the hub was damn near siezed on the spindle. In the process ruined my front axle stub shaft and the threads on the spindle are messed up from where it looked like someone cross threaded it on.
couple questions Where can i get a replacement spindle, i assume this is what its called here is a picture. Does anyone have some extras laying around? http://i114.photobucket.com/albums/n...psc6dde9f6.jpg Also one of these nuts where split as i tore it apart. Where can i get replacements? part numbers? http://i114.photobucket.com/albums/n...psc6dde9f6.jpg Also a member has some late 72 axle for sale, he informed me that 71 and early 72 axles are different then late 72. The guy i bought the frame from said it was a 71 or 72 frame, does anyone with knowledge on this subject know from my spindle what year my frame and front axle are? Thanks in advance. |
Re: 70 GMC 4wd version
I'm at work right now but go take a look in my build thread, i replaced both of mine on my 72, they if i remember correctly were manufactured by Yukon. There are 2 different sizes if i remember correctly, the bearing journals tell the size story, need to be able to mic them. I'm pretty sure still have both of my old ones but as my post states there is a bit of a lip where the bearings ride. I'm pretty sure i can find the part number. I'm sure any local 4X4 shop could order them but if i can help you with the part number you may find them cheaper on line.

Re: 70 GMC 4wd version
Totally agree here. I did the sandblast epoxy on a hard offroad wheelin Toyota that I had. After 6 years it still looks great. I used a 2 part product called endura.

Re: 70 GMC 4wd version
My replacement spindles were Yukon YP SP706529. Brg journals were 1.625 and 2.0. Cant help you with the nut but Yukon should be able to help.

Re: 70 GMC 4wd version
Cant remember for sure sorry, pretty sure they were the last change before the 73 version, like i mentioned its the bearing journal sizes that tell, i believe in 73 the bearing size went up in the inner bearing but don't quote me on that.

Re: 70 GMC 4wd version
Does anyone know of a tank like this but with a 90% fill so I could run a stake fill.

Re: 70 GMC 4wd version
Looks like your axle has endured some abuse, you might want to check the axle housings to be sure their not bent. The one that came with the stock frame I bought for this same purpose ended up with a 1-1/2 inch bend/sag in it from hub to hub. He'd to pul everything apart and have it straightened and welded again.
Cool story line with your build, cannot wait to see your complete 4X4. |

Here's a link his Chevy tanks, he has side fill or bed fill as well as EFI. He also has his tanks distributed thru different venders. http://www.fueltankparts.com/replace...evy-tanks.html This Google search lists a bunch of forum threads on his tanks: https://www.google.com/search?newwin...50._WjLsxoFw48 |
Re: 70 GMC 4wd version
Swamp rat I just looked at all those and your thread. Do you have a boyd tank? I seen at one point he made a 4x4 one but dont see it on his anylonger.

I'm sure he can still make one for a 4X4.
Yes i have one, i'm not finished with the install tho, i have been battling being sick all winter and its wearing me out, i hope to finish the install this spring. I also don't know a part number and the receipt is buried somewhere, i'm sure if you called Boyd he could provide the info. EDIT: I should add that being as i have a K20 i think the frame is a bit different from a K10 frame, the distance between the upper and lower flanges are different. Don't know if you have a K10 or K20 frame. Here's a pic of the install this is with the flanges of the tank bolted to the bottom of the frame, this actually put the 90* fill about 1/4" below the top of the upper frame rail, the only way to raise the tank now is to ether have a welder move the flanges down a little on the tank or cut out the rivets to the cross member, remove it and slide the tank in from the back putting the tank flanges between the frame rails. Or i could just take a torch and heat the frame rail up and bend it down a little to gain a little clearance for the rubber gas hose to keep it from rubbing on the top rail. |
Re: 70 GMC 4wd version
Is that the tank he list for a 2wd
|
Re: 70 GMC 4wd version
I dug up the original group buy thread Boyd did, after reading it again yea i think it is a 2wd tank. I got mine a few years ago so there could be some changes thru the years.
The group buys are now thru this thread, contact them to see if its still going on. http://67-72chevytrucks.com/vboard/s...ight=Group+buy |

Re: 70 GMC 4wd version
been busy, this last month i have been having alot of family problems, but im back at it now. thursday I got the front axle put back together so i rolled it outside friday after work (man that felt good to see it rolling again). After that friday I pulled the engine out of my truck. 468, scat forged rotating assembly, 781 reworked heads, 10.1 compression.
My plan is to clean it up and paint it then swap it in the frame. I am hoping my 800 dollar headers are going to work on the 4wd frame. Time will tell. http://i114.photobucket.com/albums/n...ps3e22bab6.jpg http://i114.photobucket.com/albums/n...ps2b8fb978.jpg http://i114.photobucket.com/albums/n...ps78be840d.jpg http://i114.photobucket.com/albums/n...ps283ded4d.jpg http://i114.photobucket.com/albums/n...ps1e76bd04.jpg http://i114.photobucket.com/albums/n...psfcc98fa2.jpg |
