Anyone out there know of a body (aka assembly ) manual for 1955? I have the shop manual, but it is limited on the body aspects...loooking for something with nice breakouts of window regulators...things like that

Does this even exist?

 

In the '50's + 60's, there was so much interchangability, almost any GM book from '55 will show the same thing, if you can't find one for an Olds!
As far as doors, anyway.
