I have a 77-79 Nova Tach and gauge cluster. I think 75-76 are different but I'd like to know for sure. It has between 3K-4K original miles on it and it comes with the clock and all of the gauges. It is in excellent condition. The tach works. I wanted to know what this might be worth? Thanks

It depends on the tach. Some were for 6 cyl engines, some for V8's. There is not a switch on the tach so one won't work for the other.

I have a 78 V8 tach dash I tried to sell for $150 and no one bought it. It wouldn't fit the 75 I had at the time. Since I now have a 77 it will be used.
