Just "inherited" a dash pad from a friend and it has markings like Mike posted, as well. Pretty faded, but it looks like 11/17/67 on a Norwood car with a late December build. No inspection stamp. It also has crayon markings of 6-0-? (can't figure out the last number). He has no idea if it is original.
Any ideas about how far in advance that interior pieces like a dash pad came into Norwood?
