My brother is almost finished parting out a 65 Parisienne hardtop. He was going to scrap and crush what is left, which is basically the chassis but since the frame seems solid and straight I thought I'd check to see if anybody needs one. It has the complete front and rear suspensions so it does roll but it is only a 10 bolt rear end, oddly enough. The car was a 283 Powerglide so it is likely a 3:07 gear.
I could take a closer look to confirm stuff if anybody is interested.
If there are no takers and the chassis gets trashed, I'm always on the lookout for the rear spring hold downs. They're the conical type pieces that hold the bottom of the rear springs onto the lower control arms.
I was just gauging interest. if you are serious I'll have to have a closer look to make sure its solid but I would think maybe a couple hundred, but you'd have to come and get it.
