My fathers frame off restoration of his 70 GS
455 buick Stage 1
Done at Orchard park collision, took a little over a year, original frame was shot, they had to get a chevelle convertable frame, since there are no GS convertable frames to be had anywhere.
Car now has headers and 3 inch stainless exhaust, converted for the N25 tips. Very rare car, well worth the money to do this. Too bad he wont let me drive it
