I have the M2300K brake kit installed in my 5.0 and now I would like to upgrade the rear end to a 31 spline set up. The axles that came with the brake kit are F4ZZ-4234-B’s which I believe came with 94 Mustangs and are a little longer. Would I simply be able to buy 31 spline axles for a 94-98 and then use a 31 spline diff for a 79-93?
