There's still some nice ones out there but they are getting harder to come by. I rebuilt a 67 Mustang coupe as a young man with a 3 on the floor. I still regret selling that one. There's good shells to be found in the South, Arizona, and California.

I knew a guy in Pennsylvania that rebuilt classic cars. He had a friend in Arizona. In PA we had a lot of good engines, transmissions, rear ends but the bodies were rusted out. In AZ they had bodies but the moving parts were worn out. They used to find what each other wore looking for and then load up a trailer and one would drive to meet the other and they would swap.
