Anyone know the original GM 67-69 part numbers? When I bought the 67 years ago, the tach was not on the car. The owner said one night someone tried to pry if off, but his dog scared them off. He removed and put it in the house. Not sure its actually from the car. He had 2 the same color, but said this one was from that car. He also had a 68, but I didn't know about the height difference back then. Never thought about be till get'n ready to restore the car after years of abuse and rust. It needs a new lens and seal, etc. If not the correct type, will just buy a replacement.
