Looking for a replacement good original Aqua Meter Tach for my 1976 CVX-20 Jet, 455 Olds. Reference picture below. Looking for an exact match if possible. Size requirements... width of tach (inserted portion) 2 and 15/16th inches, fits into approx 3 inch opening, with bezel being approx. 3 and 3/8ths inches wide. The bezel can't really be wider or I would have to cut out some of the dash panel because of the forward angle immediatly off the sides of the Tach. I don't really want to do that. Any help is greatly appreciated.
Also, does anyone have good contact info for a reliable instrument repair shop to fix the one I have? It doesn't go below 1000rpm's on dial when installed and running and will stagnate at about 3,500-4,000 and won't go higher, and does have a tendancy to jump around.
Thanks!
Mark
