8 3/4 Rearend Question

ramcharger said
It's in a '79 and it is definitely an 8 3/4. I have no idea wether or not it's factory stock though.

If i remeber right the 8.75 rear was ended in 74 or 75, but someone could have put this rear in a 79 ramcharger. Ive seen 8.75's in cars that shouldnt have been in, usually rears go out and just get replaced with an earlier 8.75
