This axle uses HSP 02024 DIFF and 02030 pinion. If you want to lock the diff you may use Axial's AX30500 heavy duty locker.
You need 6x 6700 bearing and 2x MR105 bearing. To keep it together use 7x M3 bolts (10mm) and nuts.
Input shaft to pinion must be metal, this axle will not work with the original 3d printed input shafts. This is the only restriction, all else can be stock.
If you decide to buy metal u-joints for steering (which I highly recommend, 5mm holes) you can find a drawing of the matching half axle and wheel shaft. You can try to print it in plastic, but I do not think it will last.
