Cant think of any parts that will interchange mate, its a pretty specific beast.

Your diffs are one to baby, spares are rare, i think youll have no worries wirh diff balls, but the main races, and thrust races are rocking horse poop.
The screws do snap too, but id bet you can remedy that with an M2 cap head, and put your own locking kink in it.
Just buy the toughened screws though, not the cheapie stainless.

Everything else, is a case of trawling Ebay daily and try pick up a deal, a lot of 94 parts get snapped up quick, but a short few months got me a nice tidy collection of NIP parts, so it is doable, just takes time.
