Re: Restomod 72 K10 "Good Memories"

Happy with progress, removed most of the front suspension today. Just need to get the front hangers off and should be last of rivet removal (10 more). Picked up a new IR long stroke air hammer. With an X cut in head of rivet I can have each one completely out in 2-3 minutes including the cutoff wheel work. The thin 3" 3M GreenCorps wheels are amazing. Expensive but last and cut steel like butter saving lots of time and mess. Did some initial mock up of front components. Looks like I have some fab work to get the front done. None of the suspension brackets are direct fit. Kind of expected, will be fun figuring it out and making it work.

Re: Restomod 72 K10 "Good Memories"

Frame link brackets are installed. Required crossmember modification and a bit of welding. Axle link/shock brackets are trimmed and massaged to fit the new axle. Left bracket is pictured, right passenger bracket was designed to key into spring pad with a Ubolt, Spring pad does not exist on my axle. I cut the ubolt section off and will modify that bracket as needed. Idea is to modify and move link mounts closer to knuckles to avoid welding to differential casing. Welding to cast can be difficult and not as strong. Will see if this is possible. May still need to attach to cast section where axle tube is pressed in. New wheel studs and other odd parts arrived from Summit in one day. Can get temp wheels on axle to help in checking clearances before I weld up axle brackets and make link bars.

Re: Restomod 72 K10 "Good Memories"

Have been getting work done. M14 studs and 14" Ram rotors installed along with caliper brackets. Axle link/shock brackets are totally finished and tacked on the axle. The right bracket from ORD required a lot of work to modify. I will be able to hit the plug welds when welding up giving more confidence in strength. Have a 2lb roll of specialty cast mig wire on order to do the weld to third member. Was pricey but safety is a number one concern. I made some mockup links from pvc to locate the axle. Installed the 2wd core support mounts obtained from the parts section.. Will get core support, fenders and temp wheels mounted on Monday to check clearances. Axle is pushed forward over an inch and want to be sure things work before making the links. Cutting them wrong will just cost more time and money. Hoping to get parts for tierod next week. Will get new steering box attached and determine what is needed for parts for it. ie correct pitman arm and ball joints.

Re: Restomod 72 K10 "Good Memories"

Have the axle in place. As thought it was to far forward. Moving it back shortened the links so I moved the mounts back 6 1/2". Link mounts are right on the trans crossmember now. Welded up the unused holes. Links, panhard and tierod are made. A lot more work than it looks like. Cutting pipe and drilling for plug welds takes time. Everything is just tacked together right now incase I need to make changes. Installed ported PSC steering box and brace. Pitman arm and drag link parts are on order. Need to get accessory drive on motor and a/c box installed to start on shock mounts.
Decided to use my original core support as I will be cutting a cold air intake through it. Took to body shop and pounded the damage out. Still need to clean and paint. Pleased with the progress. Working tomorrow so will not get back to it until next week.

Re: Restomod 72 K10 "Good Memories"

The motor accessory drive is installed. Had to dismount the blower to remove the snout and install upper pulley and hub. I also replaced the factory spring isolator from the snout to blower with a solid aftermarket type unit. It is a common wear item, the factory unit was shot. Blower belt sent with kit is to short. Emailed LSX Concepts and they replied quickly. They are going to send the correct belt with return label for wrong one. Great service from them as the kit was probably purchased over a year ago.

I need to measure for the serpentine rib belt and order. The power steering pump and pulley is a made to spec unit from Turn One and not from LSX Concepts. A belt was not included in the kit.

While blower lid was off I installed the 1" spacer. Supposed to increase flow. It increases plenum volume and helps correct the lean condition on the 2 rear cylinders that is on the LSA Camaro lids. Stated hp gains vary from a negligible 5hp to over 20hp. I have the room to install the spacer and I figure that it cannot hurt. Should have took more pics while disassembled but tend to forget when I get into the work.

Re: Restomod 72 K10 "Good Memories"

Been doing some work that pays. A little time for the truck. Replacement Gilmer belt arrived today and I threw it on. Figured out correct fan belt and installed a few days ago. Used the string measuring method around pulleys and the measurement was several inches shorter than belt provided with kit. PS pulley in kit is 5.2" and mine is 6.5" so i knew it was wrong. Found the next three sizes up from kit belt available local. Picked them up, two sizes up was perfect and I took the others back.
The Gilmer setup is not needed as I am only running about 10 psi of boost. Only reason is I always wanted to have a vehicle with a roots type blower and old school blower belt setup. Just think it looks cool. Can always go to the rib type belt if I do not like it.
Initial mockup for front shocks. Need to get steering sorted out so I can find final frame panhard bracket location. Local 4x4 shop let me use several pitman arms for fitment, none of them seemed to work well. Ordered another one that may be here tomorrow.
Ordered some couplers and studs to raise the engine cover mounts so it can be used with the lid spacer. I see that most just ditch it when running the spacer. I like it.

Re: Restomod 72 K10 "Good Memories"

AWESOME work Richard! That thing is gonna be really bad ass when it’s done. That four link looks like it came out really nice. Are you going to do anything to brace up the track bar mount on the frame? I’ve noticed my frame twists a little bit with just the steering box, seems that could be a weak spot on yours if you don’t brace it to the other frame rail somehow. I’m gonna put the ORD steering box brace in mine, it’s already got the weld on ORD crack repair plate.

Thank you for the kind comment. Helps to keep me motivated to post progress. I used the ORD brace on this 72 and also my last one. Can be seen in the steering box pic a couple posts back. Need to clearance a bit for the Gilmer belt pulley on crank. Little to close for me. This truck as well as my last also has the factory steering box frame reinforcement inside frame. Had no problems with the frame on my last truck.
The back edge of the panhard (trac bar) mount is right on the engine crossmember so I was thinking it will be good. I used an extended/offset mount to make the trac bar longer, which is always better. Think it will relieve some stress on frame due to design. Can always add a bar to other side of frame or maybe a triangulated brace to the engine crossmember somewhat like the ORD steering brace. Going to upgrade the panhard ends and bungs to 7/8" thread from the 3/4" ORD provided. Also going switch one end from a heim to a Johnny joint. Heims have their place, but on a DD or mostly street truck IMO not a plus.
The third pitman arm is on the way. High hopes this one is the ticket.

Installed the factory A/C box on fire wall. Going to make coilover mounting hoop a real challenge on that side. Really do not want to use a cramped, hard to service aftermarket cycling clutch system with electronic controls. The challenge is making me reconsider my choice to use the factory A/C box.

Re: Restomod 72 K10 "Good Memories"

Yea that is a tight fit for sure. Good plan on the Johnny joint, I had helms on an adjustable track bar in my old 4” lifted grand Cherokee. I could never get more than a few thousand miles out of them before they started loosening up and the death wobble came knocking. I threw that one in the trash and got a bar with hard bushings. I ran Johnny joints on the frame side front and rear upper and lower control arm bushings and they did great.
I may not post every time but I’m certainly following along, as I’m sure others are as well.
