I own an A-body and a B Body, but new to E-bodies. So lots of questions to follow. I bought a stalled project, all the metal work is complete. Still lots to complete, but up for the challenge.
Having worked through the alphabet. You know your next steps in order are to finish body and paint. Vinyl top if it has one then headliner. Front and rear glass to be installed. All the rest are just nuts and bolts. You are lucky to find one in this condition. Ask questions there are knowledgeable members here.
