68-70 Dodge B-bodies have different leaf to quarter panel distances than the 68-70 Plymouths.
i'll check to see what my dad just put on his 68 gtx. i believe his are 275/60/15 on 15 by 8 mag 500. wont be home til next weekend. also if im really really bored i'll put mine on his and see how they fit. my guess is plymouths have a smaller distance, but am not sure.
