How to make a S14 VLSD fit to a S13?

[Crab Walker]

I know that the shafts are the same, but the size of the bolt housing look alot larger on the s14 VLSD. http://rbmotoring.com/albums/partsforsale/apb.jpg

On my S13, the bolt housing on my S13 open diff look about this size.

The S14 diff should've came with bushings for the nose. If you don't have them you'll have to get them or make your own.

Look to bushings 19, 20, and 21 here:

You also have to swap the rear covers as the S13 uses 4 bolts and the S14 uses 2.
