The last pics are of the back tin where the speedo mounts. This is on the one I am currently working on and I changed how it's mounted, works out better this way.

so. question for ya. this threads super long now so i'm its been asked before but what would you charge a guy to do this to his cluster if he sends it to you minus the cluster cover face?
ive got a 67 tach cluster and am doing an ls swap and your quality looks way better than what I could do im sure

Well, you're right, it has been asked before and the answer is always the same, I cant do it. The problem is it's only really a cost effective way to go if you do it yourself. It is a bit labor intensive, so by the time I charged you to do it, you would be able to just go out and buy a new set of gauges. If I wasn't super busy all the time I would maybe consider doing a few, but really just don't have the time. Sorry.

dude thats sweet, subd!

[JPsChevy]

I've read so much my head hurts. I have a couple questions.
1) I'm running a 4.8L with a new style 2006 nv3500, can i run this with my setup?
2) Are you still selling templates or is someone else?
3) Is anyone making a complete kit on here?

Thanks

1) What year is your 4.8? If its a GenIII then yes, it will work.
2) Yes, I still have them.
3)No one is making a complete kit, but the parts are pretty easy to find.

My 4.8 is a 99 or 2000 I can't remember for sure, the nv3500 is an 06.

It will work on a 99 or 2000 no problem.

Hi Eric,

I have two questions for you-
does the LS motor run at a higher oil pressure than the old Gen1 350? if so, would an 80# oil pressure gauge be better to use (for keeping the needle mid-scale) instead of the 60# one ?

Also, what is this ?

[ls1nova71]

I think oil pressure is more dependant on how good of shape the engin is in, but mine do seem to run a bit higher than the older engines. My gauge goes way over to the right on start up and stays to the right most of the time, so if you want the needle in the middle an 80# gauge would probably get you there.

The black box on that cluster is a relay I was using for another purpose, you wont need it.

[Steve Cole]

Thanks for the reply Eric!

[Bucky10pt]

Eric, do you have a kit available? I'm getting ready to build one

How can you get the mileage to match current speedo?

I'd be interested if lens kits are still available.

Thanks

I am currently working on the wiring for my speedo swap and it appears in the photos that a relay is used in conjunction with the volt meter. Is that required?

As to Prodjays question about the odometer I just reset mine yesterday. It's a little tediuos but it's not that diffucult.

.

No relay is required for the voltmeter. That relay in the pic was part of an automatic headlight set up that truck had.

I don't really know how to explain it, but you just kind of have to mess with it a bit. Once you take it out and play with it, i think you'll see how its done.

Thanks to Ls1Nova71 I have started on my Squarebody swap to digital, even though I don't need it yet. Look at how close the S10-Speedo lines up with the Squarebody speedo bezel. Looks like the only thing I will have to modify is the odometer hole as it is a tad too small for the Odometer out of the S10.

The screw holes to mount the digital speedo even line up!

You should be able to move the numbers for the odometer over by sliding them on the shaft they're mounted on. Just have to be sure the gear on the end still makes contact with the drive motor. If it doesn't, you can add another gear to it.

As a new '78 Squarebody owner, I am very interested in knowing everything that's going on here. Please let me know.

this speedo you made does it do a full sweep? or does it stop at 100 like they do in a s10?

It stops at 120, that is where the little stop thing is. At least I think it should, to be honest I have never had the truck above 100. When you say S-10's stop at 100, is that all the faster the truck will go before the speed limiter kicks in, or does the needle just stop there? I can't remember if there is a stop at 100 on the S-10. EDIT; I just looked at my S-10 speedo pic, and there is a little stop at the 100 mph mark that keeps the needle from going any further.

[1970 C10 MJW]

so we then assume with the needle bump stop moved down that the speedo will then go up to 120?

Yes, it should. I do know that if you remove the stop the needle will go all the way back to the bottom of the first stop, but they can sometimes get stuck, that's why there are stops.

Nice job. Another thing to add to the ever growing list of projects. Thanks for taking time to share this great mod.

[chevy72blu]

I'd be interested in buying one of these as well.

You could easily have a business on your hands with not just these, but other classic vehicles that are popular with LSX swaps.
