The excellent GM Heritage Center in Sterling Heights Michigan, (which I have been lucky enough to visit
see previous post here), has excellent online documentation to assist with restoration or anything else you’d like to know about your GM product.

My Wife arranged a birthday visit for me to the excellent
GM Heritage Centre in Sterling Heights Michigan. a while back
The collection of vehicles at the centre is superb, some photos can be seen in the gallery.
All of the famous concept cars such as the Buick Y Job, Buick Le Sabre, Mako Shark, and the various Firebirds.
Most of the GM output of the last century across the various brands are well represented, in either restored or original form.
There is a great neon advertising display, along with a comprehensive engine and transmission displays.
