7K 73-87 tachs - The 1947 - Present Chevrolet & GMC Truck Message Board Network

1985-GMC · 01-16-2012, 01:37 AM

I just stumbled across this site where they referb and convert them over to 7K. Im bet their pricey since they don't list a price but they sure do look good.

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.

Telecasterjoey · 02-13-2012, 11:02 PM

Those are pretty sweet didn't know anyone made a reproduction tach ! Gonna have to get one!

Those are very nice. only one problem those are for the 81 on up body style gauges i need one exactly like in the picture seems like thats going to be hard to find.

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.

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.

I agree with Jknight. They are plastic but when installed they look great.Heres mine

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

**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

Diesel tachs are 4K http://www.ebay.com/itm/1986-1988-19...item53ebb69f4c
GM part number 25054948

**Dieselwrencher** · 02-25-2012, 12:06 PM

Thanks for that! Do they have them without the fuel gauge?

1985-GMC · 02-25-2012, 02:48 PM

Im not sure, I can't find any pictures of one. ^ That one is out of a medium duty truck btw.

MalibuSSwagon · 02-26-2012, 02:07 AM

homemade87, the tach looks great! One of these days I'm going to pick one of those up. For now I'm rocking the tach on the column.

The other day I pulled a tach/vac cluster out of a 70's C65. Got it for $20! Putting it up on ebay, no interest in making it work in my 86 C10.

Good score on the cluster. What you sell it for will go a long way on the tach unit. I agree not converting everything on the cluster.
