AZ I REALLY need a tach circuit board for a 76-77 cluster! - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**1774btcrew** · 09-23-2014, 02:38 PM

If anyone could help me out, I would really appreciate it. I have modified my cluster for aftermarket speedometer and tach. I have a 4l80e transmission and it requires and electric speedo. Doing this involves cutting an unused section out of the circuit board to clear the speedo. The GM part numbers that will work are either 8917776 for early 1976 and the late 76 - 77 one is #25015093. I have several tach clusters and the only one I have the correct year is MINT. I can't justify cutting up the circuit board but will do so if I absolutely have to. Trying to avoid ruining something really nice.

I have one outnof my 77 c30 with a cluster, but it is kinda rough ariund fuel guage. It's in my truck now but has no wiring hooked up to it.

These aftermarket circuit units are really pretty decent...

Thanks for the link I will probably buy from there. I knew LMC had them but I haven't been happy with anything that I have purchased from them

I have a complete tach cluster with that circuit board in pretty decent shape $125 for the whole thing if interested.
its the 1776 #
As always the tach was said to work, But I did not try it.

Tom, I got the circuit board that I needed. I just paid the $80 at Classic industries. I can't see messing up a nice cluster just for a circuit board! Let Chevy1966 have it if he wants. Thanks for the heads up!

Tom,

I'll take your 1977 cluster panel! I have a 1977 with the large fuel guage and would like to use this to add the tach and small fuel guage. You can contact me at jcwoodworks@charter.net or text/call 612-384-3821.
Thanks,
