new build need some help

[Sonic]

I have a murray explorer frame I'm going to put my predator 420 on and it's basically a bare frame so I need allot, First I can't seem to find the right spindles for the front wheels, second I have a 5/8" jackshaft I could make work but I don't know if it's to much power for that small of a jackshaft, then I need an axle and bearings and didn't know if anyone knows the right size axle I'd need

Your axle size depends on bearing size which depends on the flange size.
