Welcome to the board Bogasracer.Your pick of a serial number for example is to close for comfort and very well could be an A12 Super Bee (306999) because most of the other serial numbers that begin with 3069** are all A 12 Super Bees. You speak of quality in production, and I was wondering if it really existed back in 1969 in Chrysler Production with the way these car came off the assembly line.The inspection marks differ all the time some are ink stamps others are punchs others just say OK and then there are all kinds of numerical numbers or letter that belong to the inspectors in each group or at the end of the production line after roll test.Keep posting on here you insight into production is appreciated.
