wich axles from summit there is two there not sure wich one i want

first question... do you have a 31 spline possi unit?

these stangs are 28 spline unless its already been converted over. has that been done? else niether one of those is right

otherwise in my catolog, the ev80 is listed for the fox body (79-93) and would be a different length i believe, so the ev83 would be right if it has been converted and ev83-28 is correct for stock application.

oh and slightly off topic, but why are they listed as having a corrosion resistant finish? dont these things spend there life laying in oil. well as long as it is driven.
