I have the S15 HLSD with the correct 6 bolt output shafts to match.

I also got a complete J30 R200 diff (5 bolt outputs) from a '93 or 94 to use the 3.91 ring & pinion.

I have a non-abs S14 (stock driveshaft). I know the HLSD should be a direct fit, but since i added a good amount of power, the 4.08s seem a bit too short which is why i went for the 3.91s.

I'm about to tear the whole rear end down soon to do all the bushings poly/aluminum and put together my ideal R200, but now i'm a bit unclear if the J30 R&P is going to work with the "ring thickness" this and "housing length" that, then J30 axels or different driveshaft if the correct housing is longer? I thought i was confident before i bought it, but it'd be nice to make sure before i do if anyone cares to confirm or deny for me that the J30 R&P is gonna fly...
