The 70 and the 71 are different because of the signals being in the valance,like a Challenger and the opening above the valance being smaller.I have seen 70 bumpers on 71s.The frt could use the work of a pro to straighten it,but can be done.The rear needs some work on the urethane coating,its still gonna take some time and money to get these real nice.
Shipping both of these bumpers is gonna cost quite a bit to get them to you,there heavy.
