9" ford rearend

[akitagandy]

Is there a way to tell if a 9" rearend is a 31 spline without going into it

Not really. Most PickUp trucks (not all) had 31. You can try deciphering the tag but there seems to be dozens of codes and I've never been to successful at that.

Go here with your diff tag it lists alot of them how many splines.
