OH, I have many repair manuals, a factory 1974 Service Manual, 1980 Electrical Manual, 1986 Electrical Manual and Chilton's and Haynes Manual. But there are no Factory Assembly Manuals.
I've restored a 1957 Chevy BelAir and a 1960 Impala the both have a Repair Manual and an ASSEMBLY MANUAL. The Assembly Manual shows the Assembly Line how to put the vehicle together.
I'm looking for something in a little more depth for a concorous restoration.
