difference between a 72 and a 73

[makovai]

12 bolt - other than the spring perch distance and the shock mounts were the 1972 and 1973 12 bolt rear ends the same?

I have a guy on his way, and he wants the ring and pinion from my 12 bolt but i'm not poistive if the pumkins were identical.

Same animal as you've stated, all 12 bolts are the same so long as we're talking truck 12 bolts, the car 12 bolt is completely different and nothing interchanges.
