I have a 71 gran coupe 383 2bbl with 2 fender tags that needs resto. I found there are 161 383 2bbl gran coupes built. Is there any way to break it down further? It's gY9 with the off white leather buckets, white vinyl top, luggage rack, road lamps, 6 way seat, console auto, power windows, steering, brakes, rimbliw, AC. I have always been curious if there was any way to realistically break it down a bit further than the 161 built?
