Is it true that '65 and '66 full size Pontiac differentials differ from all others? I was told that these two years are impossible to get after market ring and pinion sets because of non-standard mountings. If so, can I substitute the entire axle housing assembly with one from a '67 or newer one that I can get available gear sets for?
