There are "assembly manuals" out the for the tri five Chevys.
Can anyone tell me when these manuals came into existence?
Were these manuals published by GM ?
A question came up, regarding the ability to interchange frames between 1955 through 1957.
My 11/1/57 GM Parts Catalog Manual shows one frame for '55 through '57, except for convertible. Footnote shows a different crossmember for Turboglide models.
I am told SEVERAL frames were available, as per the "assembly manuals".
When did these "assembly manuals" arrive on the scene?
If several frames (part numbers) were available, but the GM P & A Manual only shows one part number, how would a guy, say ... back in 1957, get the correct part number for his 1956 frame, as an example?
I worked in GM service for way too many years, but never saw an "assembly manual" behind the parts counter, as a source of part numbers to order.
This has got me stumped.
