modular clutch availability?

Hello, it's so hard to really know. I did a web search and found a couple leads -- I suggest you do the same and then reach out to the places that list possible fitting parts. Ask questions and dig and I bet you'll find that needle in a haystack. Also, see if you can find a manual drive train specialist near you - they may be able to even rebuild your existing components? Hard to say, but if you have no further choice, you have to ask and see what can be done.
