R200 Ratio Interchangability

[ryzan]

I'm wanting to change to 3.69's in my r200, appears not too many cars ran this ratio though. I've found auto s15's have and was wanting to swap the crown and pinion into my current diff. Only problem is the s15 diff uses an abs sensor up the front. I've heard the difference is with the flange though and not the pinion itself. Anybody able to confirm the crown and pinion are a straight swap between short r200's?

They generally swap fairly well. Need to be set up properly though.
