Alright here we go, my buddy is trying to get his truck together for Bloomsburg Truck nationals this weekend. He has a rear axle out of a 1985 Chevy Blazer, an SM465 with an NP205 out of a 70 something and a driveshaft from a 77 burb shortened up. The shaft has a 1310 on the axle end but the axle isn't a 1310 joint. What joint would the axle be? It doesn't have tabs so the joint has to have inner clips that hold it in place. After an hour at Autozone we figured it was some Cleveland P55 joint and they couldn't get us a conversion joint fast enough. Anyone else have an idea?
