Not my car, but one that we did a lot of work on. It's a 67 convertible with a C4 and 200 6. Customer wants a tach (I know, a 6 cyl auto) in the middle of the dash that has a small empty slot (unused clock hole?). I haven't seen the car yet, but I don't know if 67s had a tach available, or if it had a different dash bezel if they did. Or did 67s use external rally-pacs? This is also running the original breaker\point ignition and a complete Painless wiring harness. Sorry for the ignorance on the 67.
