Liddy71 · 01-16-2012, 02:16 AM

looks like about 130.00 not bad to have it done

Jonboy · 01-16-2012, 10:36 AM

That is too cool.

**N2TRUX** · 01-16-2012, 12:37 PM

Looks like a great source. Theres a guy on ebay that sells complete replacement units that are nice too. Unfortunately they don't match all the different styles of gauge fonts.

1985-GMC · 01-16-2012, 10:58 PM

Oh this was on the price list:
1973-1987 GM/GMC TRUCK TACH REPAIR,RESTORATION: INSTALL SOLID STATE TACH BOARD, $175.00, 2 YEAR WARRANTY, REFACE 5000 TACH TO 7000 RPM, $80.00, REPLACE METER COIL, $50.00.

1985-GMC · 02-13-2012, 12:28 AM

Another site with reproduction tach/ gauges. http://www.justdashes.com/ReplaceGauges.htm

And this place makes replacement circuit boards for corvettes and our trucks, when you order you have to put in the comment box to note that your ordering for a chevy truck. http://willcoxcorvette.com/product_i...ducts_id=26788

And this is a different site but it has all the same stuff as tachman.com http://www.instrumentsrus.com/gm.htm

BamaDave · 02-13-2012, 02:24 AM

I had my tach done by Wilcox. VERY HAPPY! 50 bones + ride= new board and calibrated!

54Caddy · 02-13-2012, 02:28 AM

Anyone have info on finding a tach like the one pictured with the small fuel gauge on it.

The one I got with the fuel gauge in it was from www.gmsportsalvage.com

Edit... I can't get the right link on my phone but there is a thread on it. If no one links it I will tonight.

Yes the face is plastic instead of stamped metal like the factory ones but when installed you cant tell the difference.

I just found 2 complete clusters with the tach/fuel gauge at a local salvage yard today. I could grab them both if someone was willing to pay for the part and shipping? Pickin old trucks is a hobby of mine. They are 81-91 GMC 7000 clusters.

You should get them anyway if they are cheap.

Telecasterjoey · 02-13-2012, 11:02 PM

m00n1957 · 02-14-2012, 10:10 PM

i have a factory tach cluster from a 79 4x4, but i think i'd rather have one of these.

1985-GMC · 02-24-2012, 08:33 PM

I fixed my tach with some help: http://www.gm***************/forum/s...ead.php?t=2281

Edit: ^ that is supposed to say "gm square body. com" with no spaces

I Can't believe I got the old tach I had laying around working! I looked at your post and thought I'll give that a shot on my blown tach.

went to the electronics store got the potentiometer came home put it all together and couldn't believe it! the tach never came close to working before. I'd hook it up and it would just bury the needle. I had an autometer tach laying around and I was able to tune the stock one to match. What a badass idea! I cant believe more ppl don't know bout this mod. Even if your tach works you could add the potentiometer to dial it in!

I couldn't get the pot to lay flat enough on the circuit board to seat the tach into the plastic properly so I just glued it to the back of the tach face and ran some wires to it. I love my cluster now its got everything! Clock and tach

Ps. I got the tach a year ago at the junk yard and was super bummed when it didn't work.

Sorry for the crappy pics my garage is dark and I only had my phone camera.

Thanks a lot man!

MalibuSSwagon · 02-28-2012, 05:31 AM

That looks great joey! I dream of the day I find one in the junkyard.

Chevyman350 · 02-29-2012, 05:11 PM

I Contacted Wilcox and the truck board is 88.00.

Due to the their expernece with truck parts vendors not expressing intrest in carying this part.

Here is the link.

http://willcoxcorvette.com/product_i...ducts_id=27330

I will buy one for sure but I was hoping LMC, classis industries, etc., would want to carry a part like this?

Oh Well

**Dieselwrencher** · 02-24-2012, 09:26 PM

Those are pretty cool. I need one to read to 4k only. I wonder if they can do that?

1985-GMC · 02-24-2012, 10:01 PM
