My diff is, I think, out of a S15 and has a shimmed solid pinion gear spacer. Others have a crushable spacer which does not need shims. My first question is, can the crushable spacer be used instead of the shimmed solid spacer? Second question concerns parts availability, I've been told that one particular bearing is a Nissan special which is only available from Nissan and has been unavailable for months.
A complete kit is needed, bearings, spacer and seals. Any reliable sources?
