If i was to get the '95 SR axle, i was planning on cutting of the coil perches and welding on leaf spring pearches. But if by some stroke of luck there was a sport axle along with that SR axle, it wouldnt take to long to swap the SR diff and axles into the Sport housing(joy of 3rd members and lack of C-clips). Now.....if a 90-93(i think this is the year range) SR axle is at the yard, is it a gaurante like the 95 to have an air locking diff, or pretty much see if the button is there for it?? And the difference between the 93 axle is a smaller ring gear(9" vs 9.5")?? Thanks for all your help and information guys, you guys really are helping figure out the axle situation.
