Aftermarket tach install

I had installed a camaro tach in another cluster. It quit working after only a few weeks. This could've been due to lack of a tach filter. (oops) Well anyway I won a 3 3/8ths AutoMeter on ebay. It's now installed in the dash panel that I had replaced. If there's any interest I'll post the pictures of how I did it in the FAQ.

I hope this isn't a total thread highjack but I have been doing the same thing.

A few years ago I bought a non-tach, gauge cluster at a swap meet for $1. It was missing the speedo gauge.

This spring I paid a princely sum for a tach/air gauge from the parts board. I'm not complaining about the price, they just are not cheap.

With all the threads on this forum floating around about tachs not being that accurate, and with this major cold weather, I started messing around with my pile of parts.

I took the full tach/air cluster and pulled the tach and oil/air gauges out. I took the $1 cluster and buffed the lines off the tach spot and the air gauge spot.

A week ago I found a quartz clock in the yard in a mid 80s suburban. I had a couple of hole saws in my tool box that seemed to be the right size.

The only cutting I did was to the $1 cluster. Another board member mentioned that the way to "cut" a hole for the clock stalk is to heat up a nail. I did that last night.

The cluster isn't ready to install yet. I still need to mount the tach better.

Basically all you do is cut the hole in the non-tach cluster for the tach. Cut the hole next to the oil pressure gauge for the clock. Buff some lines off the lens. "Nail" the hole in the lens. And put it all together.

If you bought a tach printed circuit, and cut up a non-tach cluster, you would be there.

Nice job mrein. I'm going to look for one of those clocks
