On my 64 when I put a 71 cross member in, The holes I needed to move were the two lower holes on the sides which have the bolts from the inside of the frame . All the bolts with nuts lined up. Those two only needed about 1/4 to the rear and 1/4 up. I just used a die grinder. I also used new grade 8 bolts.... just because the originals were 45 years old
