hello,

Has anyone used the summit retro gauges to replace their square body gauges? I am looking at replacing my large fuel gauge with the tachometer and the small clock with a small fuel gauge. They appear to mount the same on both, just curious how they look after installed. Will be going in a 84 high sierra c10


Thanks

Alex

Hey Alex, when I did that conversion I used the LMC tach kit.

I could be wrong, and I don’t know if Summit includes any provisions for just swapping in a tachometer, but I think it generally requires a new printed circuit, and also the green plastic backing plate that has a space for the tachometer plug to sneak through the back to actually get to the tachometer. Apologies for the poor photo, but the LMC kit is pretty seamless and includes everything you need. Although, it will come with the stock tachometer that goes to 5k RPM.

Thanks for the info. I was gonna go the route of pinning on the main gauge panel plug to get the wires to the new fuel gauge. And then run new wires for the tach. I found someone else post doing similar after I posted this. They used oem gauges off another truck. Although it appeared they didn’t have the clock like mine does. And just had to cut out the blank spot to fit the fuel gauge.

In a different approach, anyone aware of a small matching tach that goes in an empty small gauge location I have?

I haven’t seen any small oem style. But I believe Holley/brothers had some that will fit in the oem guage holes.

The summit tach is 3 wires off back of the guage. Ground power and signal wire. Other post on here used an inline fuse that plugged into your guage fuse panel and kept the original fuse also. And used the wire off the 2nd fuse to power the tach. Signal wire obviously goes to the distributor. So should not be to hard to get tach going. Main thing will be the wiring for the fuel guage from oem location to the clock location.

You’re likely onto something there- I’m a little rusty since I did mine probably a couple years ago.

Glowshift sells a small one that will fit if you cut the whole for it. I replaced everything but the fuel gauge. Put the tach in the lower right spot because it was easiest to see while driving.

LMC has gauges that will be a closer match.

Stock gauges

I’ll have to take a look but I didn’t think the summit gauges looked half bad for an oem style. LMC maybe cheaper though.

ah...sorry about that, I didn't realize your initial pic had the gauges in it. They look nice.

And from the looks of it, the LMC tach will require a wiring harness making it more than Summit.

Yea this tach is simple power ground signal. And just need to knock a hole in back of judge cluster box for them to go thru. Thanks though!
