Re: My New Truck
 

Thanks, I appreciated it. Sent you a PM.

Re: My New Truck
 

Interesting all of the responses of others having a 100-250 gauge. I had never seen another one.

Re: My New Truck
 

My old ‘73 c20 also had the numbers on the temp gauge.

Re: My New Truck
 

If there's one thing i've noticed over the years, it's that GM didn't quite have a rhyme or reason to how things ended up. I've noticed things like depending on what factory the truck was built. For instance the fuel gauge in my super original 82 diesel built in Janesville is different than my other 82 diesel built the exact same month but in St Louis. No indication they've been swapped.

Re: My New Truck
 

Here is a nice NOS 1973 ONLY temp gauge with numbers.

Re: My New Truck
 

For somebody who needs that I think that is a great price!

Re: My New Truck
 

Since the days are getting shorter, maybe I can spend more time in the shop. (with less daylight)

To start this fall off I ceramic Coated the Truck this weekend. After doing Tons of research I realized I have to first wash the Truck then clay-bar the entire truck before I could put down the ceramic coating.

I am hearing a bunch of very positive reviews on the Ceramic coating offered by Turtle Wax and their "Hybrid Solutions" which is what I chose.

Re: My New Truck
 

Ceramic Coating now applied.

Re: My New Truck
 

Wow that looks awesome!

Re: My New Truck
 

Thank you!

Re: My New Truck
 

Still my favorite truck on here...! looking sharp as always!

Re: My New Truck
 

Thank you for the kind words, your truck doesn't look so bad itself!

Re: My New Truck
 

This is a cool truck with great history. I love the street pics...I grew up in a house at 77th/Lamar and most of my childhood memories are of those tree lined streets and the cool cars and trucks that were parked in them.

Re: My New Truck
 

A more recent photo of the GMC Truck!

Re: My New Truck
 

factory guy,
That looks really nice. beautiful truck!

Re: My New Truck
 

So the old A/C finally gave up the ghost, it was converted to 134a back in the 1990's. Truck is getting repaired as we speak. Probably going to be a little pricey. $$$$

Re: My New Truck
 

It will be worth it though.

Re: My New Truck
 

I know that the truck is probably not seeing much in the way of weather, but I'll be interested to hear what you think of the turtle wax ceramic product as time goes on. Good luck with your AC system. Always a deep breath when you take it in and ask them to make it work.

Re: My New Truck
 

Yes the truck spends little time outside unless it is being driven or a show. Prior to me it sat it the Denver sun for 25+ years. I will keep you posted on the ceramic coat. Probably will complete the second ceramic coat this fall.

Re: My New Truck
 

Factory Guy,
Do you have an updated pic or video of this new gauge set up? I have a 77 and I am curious if I should do something similar. I do not like not having a Tach.
Thanks!
Sven

Re: My New Truck
 

Still Haven't finished it yet (life got in the way and this project got sidelined)

This winter I plan to finish it.

Here is the latest mock up of the 8000 RPM tach and the rest of the factory gauges. Tach face fonts are now the same size and scale as the Speedo (Note needles are just lying on the gauges they are not attached yet).

Re: My New Truck
 

Here is the decal I apply to the fuel gauge face. (note the bigger fonts on the Tachometer gauge now).

Re: My New Truck
 

Since you are adding a tach you are going to have to do something with the wiring. So I made my own custom plug,(the Mylar decal wiring won't work for this application) in case, this cluster ever needs to come back out. The fuel gauge will also be in this plug as well. The Squarebody plug to the laminate decal wiring will carry all of the normal gauges and their functions (I would have liked to run EVERYTHING through the original Squarebody wiring plug-but since that cannot happen...).

Re: My New Truck
 

Here's what the Tach I used looked like before I took it apart to mount in to the back of the old Fuel Gauge.

Re: My New Truck
 

Then I realized that the tach housing was WAY to big to get inside the Squarebody housing SO it had to go (And since I didn't want to cut a huge hole in the back of this nice housing-I had to find another way). Unfortunately the picture of it fitting in the Squarebody gauge cluster didn't come out the best, but it squeezed in there with minimal damage to the housing.

Re: My New Truck
 

Since several of you have ask how my ceramic coating is holding up I thought I would share a few photos of the truck. Now remember the truck only got the one coating so far (recommended is 2) and it does live in a GARAGE all of the time it is not being driven. Truck has not been washed recently. The spot in the hood is actually a reflection of the light pole above the truck.

Re: My New Truck
 

Good lord she’s beautiful!!

Re: My New Truck
 

Thanks!

Re: My New Truck
 

I guess its time for a new project as I found this the other day!

LS 6.0 LQ4

Re: My New Truck
 

well you are half way there.... now! you just need to find a truck to put it in....LOL!!!! :haha: keep us posted on the install ;).. I am curious as to what you might be planning for the wiring?:burnout: ...
still is beautiful truck!! :metal:

Re: My New Truck
 

Oh yeah!!! LS time! Feel free to hit me up for whatever information I can offer. I’ve seen your work though, and I have no doubt yours will be clean as can be!

Re: My New Truck
 

Thanks for the update on the ceramic coating. I'm a big fan of cleaning and preserving the original paint, even touching up where needed. I do it all by hand to maximize the amount of paint that is preserved. What I end up with is a good luster, but not a lot of gloss. It appears that the ceramic product could actually apply a gloss on top of the paint. Sorry, not trying to make this about my projects, but that was helpful information. Do you have a name of the product you used?

Edit: I went back and found it. By the way, I think your tach project is really cool. A great solution without pitching the other factory gauges.

Re: My New Truck
 

Update on the paint.

A drop of water fell on the hood today so before I wiped it off I took a photo.

Re: My New Truck
 

...LOL!! nice..... :ito: now! get that wipped off!:lol:

Re: My New Truck
 

LT7A

Here's what I used, about 1 year ago.

Re: My New Truck
 

Plans right now are to use the factory style wiring and ECU, we will see how that develops.

Re: My New Truck
 

I cracked open a valve cover on the LQ4, last night and I was PLEASED to say the least. I guess some people do take care of their stuff!

Don't know how many miles was on her, but this looks great so far!

Now if I could just find a 4L80e transmission that was in this good of shape.

Re: My New Truck
 

Well after MANY, MANY months I finally go my gauge cluster and the 8000 RPM Square body TACH installed and working!

A short video of these gauges can be seen here:

Looks sharp man!

Re: My New Truck
 

Thank you, it was a ton of work, way more than I would have thought, but I am VERY please with the results!
