I need to know if the front bumpers on a 72 will identically bolt on a 71?? Does the grill bolt in the same locations?? I realize the 72's have slots and the 71's don't, but that doesn't bother me. Tri City has a 72 bumper that is ready now, and if I leave my 71 it will take 14-16 weeks and either a trip back to TN or shipping on a bumper and I was just going to swap my 71 for his completed 72 IF they are DIRECT bolt on swaps.
