Ok, not sure if they have reasonably priced 30 spline one piece side gears for dana 60, 32 and 35 for sure, you may have to find spicer parts not yukon. If you look online most gears for sale are for non powerlock diffs so be careful. I don't know what axle bearings you have but you need to use greens with that short axle for sure, and make sure they are the later snap ring style. Cass can fill you in on all this, it might be best to go 35 spline internal kit and new axles, about $600. I would check the diff bearings too, as all that metal may have went thru them, at some point in that ring gears life. You could also buy new axles and reuse the 30 spline stuff.
30 spline 1 piece gear is spicer 34513, the friction plate is 42522, you will need both.
