4th gen rear end identification
So I am looking to buy a 3:73 disc brake 4th gen rear end, but while I am looking is there an easy way to ID the rear end? I know there is probably another thread on this somewhere but I could not find it... Any help would be much appreciated!! Thanks!!

Re: 4th gen rear end identification
3.73 was never a stock ratio in the V8 (posi) 4th gen rears ...
3.42 was the lower ration in the 6 speed cars
3.23 or 2.73 in an automatic car
