I haven’t really made up my mind on what I want to do with my dash. Ultimately a full Auto-Meter setup behind the factory bezel is my goal, but I need to spend that money elsewhere at the moment. Beings that I love to rummage through junkyards, I thought I might find something else that would look stock and fit in the bezel. (The original truck tach is too expensive and too hard to find!) I have heard of people using a tach from a 70s model Camaro or Monte Carlo. I also found this 69/72 Grand Prix/GTO tach online for about $50 that looks similar. Anybody used anything else and made it fit behind our factory bezels? By the way, I LOVE "do it yourself" projects
