Were do i strart

[Pratts70]

I recently picked up this 1970 c20 a guy was going to scrap it so i saved her from being crushed i asked what was wrong with it and only thing wrong was clutch was out i picked it up for $200 to my luck in the tool box was a nice 8 ton jack and newer ridgid vise i also got $50 for scrappen the tool boxes so im already ahead my question is this i have removed the rusted out tool boxes and the bench seat to check out the floor pans but this is the first project im starting is it best to strip it down and start with the frame up replacing things as i go or find all replacement body panels first then strip it down just curious thanks
