I have a MPC 70' GTO and one of the new released '72 kits in hand. The 1970 GTO bumper fits both kits well. The only issue is that it looks like the angle of the fender gap where the bumper goes needs a little bit of work. At least if you get a copy of the '70 GTO rear bumper, you don't have to cut it in half... I just checked Modelhaus, they have the '70 rear bumper for $6.75 + $5 S&H. The translucent taillights from the '72 kit fit the 1970 bumper.
