I've had my V92C for 12 years now; here's a parts cross-reference list I've made up over time. When developing the V92 series, they went to existing parts stocks for many items, which does make it easier to keep them going. The list is a general one, and some cross-references may be dated, but this should give you a starting place.
One thing to beware - the "T" quick-detach fuel fitting gets VERY FRAGILE over time, and WILL break if you put it under side loads when inserting / removing it from the lower (female) part. This part is unicorn status - listed as NLA from Victory about ten years ago. Also, when reconnecting the fittings, make sure you have the latch pushed in, or you may shave the o-ring, causing a fuel leak.
