A-Body Axles

Need new axles. Want to run slicks and dad's old hand me down SBP axles drilled to BBP probably wont take the torque.

8 3/4 rear end. Need to know spline count and length.

Moser vs Yukon? Are Mosers really worth the extra $$? I have a pretty stout 318, but its still a 318.

Im thinking these will fit yeah?

Yukon Gear Rear Axle Shaft, 28.0 in.
