Two questions about installing new factory tach in place of old fuel gage. 1) Does the back of the instrument panel have to have a major triangular hole cut into it? I guess then the three screws on outside edge hold the gage in place. 2) I upgraded my ignition to the crane electronic system including coil. Can I expect any problems with it working properly? Which side of the coil does it get wired to by the way?

Just did that. Here's the link: https://www.camaros.net/forum/ultimat...c/10/3476.html

As I'n not using factory guages in the console, I did not buy the repro tach curcuit board or guage conversion harness. I modified the existing circuit board, and will have to repurpose 1 wire in the dash harness.

The tach bolts right in in place of the fuel guage, but the circuit board needs to be reworked / clearanced, and a few wiring changes made.

I think / hope the new repro tach will work fine with electronic ignition.

The tach wires to the NEGATIVE side of the coil.

Thanks for the reply Jim. Looks like we are doing the same thing but to different years. I did not think I had to do much but butcher the back of the old fuel cavity. The factory tach has a triangular formation on the back so it can't fit in the cavity. I wonder if that mean there was a separate carrier for tach cars and fuel gage cars?

If you'll look closely at the back of your carrier, you'll see a "triangle" line that you can use as a guide for cutting it out.

I replaced my dash fuel gauge with a tach and yes you have to cut out a different hole. I thought that the tach I ordered came with a template and I believe that the mounting holes are the same. It's been a while. I didn't get a new dash bezel so I know that I had to cut clearance for the tach.

Mine is a '69 if that's what you're working on since you're "69rag327".

HI, How do you guys like using a factory tach? I have one bit its broken. I cant figure what would be better, buying an aftermarket "Autometer" or sticking with stock repop? Do anyone know the differences, plus negatives of the 2 tachs? Any input would be great.
