what five speed parts do you need and what year is the gear box?
I'd guess there are several many late model nitrided gear clusters laying around
I have the equivalent of two milk crates full of triumph four speed stuff I'd be glad to put on you for about hunnert fiddy plus shipping. It's a heavy box full and can do multiple flat rate boxes via USPS.
I'm not exactly sure what I need. It looks like I have a few different years worth of parts in there already and I can't pinpoint the exact problem. I've been trouble shooting for a while now. I just want to get on the road without more headache.
