I would bet 70 is a one year only and 71-72 are the same but will have to check assembly manuals for part #s.
That's what I think too, 70 1 year model and 71-72 the same. I only have the 71 book si I can't check by miself; Thanks David
David, I just checked my books and 70 is different than 71 front and rear. I have no 72 info but would guess is the same as 71. I can give you 71 parts #s if you need them.
Thank's again ! It's because I have found a set of aluminum bracket but, for a 70. So it's not working for me. I will have to make my own. David
