I have from the wheel arches back on the 70 quarter panels only and so I will be splicing as far back on the car as possible. I am not a professional so I may even hire a professional to do the splice, but then again I may be the one doing the deed. I did separate all the spots on the 70 when I pulled it apart it was a 4door. I actually have the full frame rails, trunk pan trunk latch bracket, bumper brackets and everything else from the trunk pan back. I have everything from the front doors forward including the front frame rails forward just because I thought someday someone might be needing them, maybe even me. I have some 69 fenders that when I get the rear quarters done I would be willing to trade for 70 front fenders just to have extras ( I have a 70 Dart hardtop also ).
