My early 68 1275 also appears to have the original diffy which is a
4.22... As I mentioned to Brad concerning other parts for these
cars, I believe they used up whatever was in the parts bins before
starting changes. They wouldn't have thrown out a bunch of 4.22 difs
just because they had a new batch of 3.9s....
Cheers!!
