90 kx250 clutch parts help
 

I just acquired a running 1990 kx250 for $100. Screaming deal, but needs some work.
I need a new clutch basket and inner clutch hub. I can not find new, used, or oem clutch parts that are available.

My question is where can I purchase a clutch basket and clutch hub? 1990-1991 have the same part numbers, but the years after are different. Are there other years of kx250s' or kx125s' that have compatible clutches?

I've tried searching for compatible clutch parts from newer kxs', but I must not have been using the right vernacular because the search results were not close to what I needed.

I've searched and searched the Internet and ebay and can't find anything. I am desperate.

Any help would be much appreciated!
