30 spline hub part and d60 locker

I need a 30 spine hub part. Its the part that slides over the axle shaft.
If its to much I may just man up and purchase a 35 stub shaft to fit the 35 spline hubs i have.

also need a heavy duty 79 d60 locker (front 60)

125$ for yukon 4340

I have two chevy hubs not sure if they will work, but you can have them

I'm not sure neither. let me see what kind of cash i can get together. Chris, that 4340 is the stub shaft right? Also how much could you get me a Detroit for?
