Does anyone know what a 64 nova 10 bolt rear should measure from flange to flange???? I took one out of a parts car I have, 62 nova, guy told me it had a 68 nova rearend in it. It is narrower than the one I took out of my 62. The donor rear is about 51.5" and my 62 is a little over 52" Numbers on the donor rear are, 2peg1452 date code e239 . It is a 8.5 273, will other ratios fit in this case????

Thanks for the info Joe
