it depends on which intermediate shaft you get..if you get teh s1/j1 int. shaft, you need to use 90-93 teg axles and you have to modify them a tiny bit(remove the dust seal and a small piece from the hub i think)
if you get the y1 shaft, you need the sir axles, which are custom made
its explained in more detail here
