I need a straight answer; s13 vlsd in s14

[UncleBen]

I searched already, and this question has been asked numerous times with no straight answers. Everyone always gets off topic and the question doesn't get answered, BAH.

So this is what I have kinda figured out on my own and with the aid of the small amount of info out there; the s13 back cover has to be changed out with the s14, and the inputshaft bolts are longer on the s14, so I would need s13 input shaft bolts. If this is right or whatever, or if I need more info, please tell me. Thanks.

I can be done. All you need to do is switch the diff. covers. The axle bolts are all the same. Question is , is it a USDM diff or a JDM diff your swapping in.
