I dis-assembled my 71 Z28 2 years ago, sent the body to Atlanta Auto Restoration in Hampton. It had a little rust and some previous not great body work. I replaced both quarters , both doors (by choice), both rockers, rear filler. As everyone knows its the prep that makes or breaks the build. The body id perfect with 4 coats of paint and 5 coats of clear. Suspension is all ride tech, T5 transmission. Every thing on the car is new Lamar racing 383. my best ques is 6 to 9 months to go.
