This is what i got diagram wise. Been trying to find a good replacement myself but looks like older sportmans may have the same setup
I actually just swapped out my primary clutch for a straight shaft.
Swapped in a 670 predator into a 06 th440c.
Shoot me a pm if your still looking id gladly sell it lol.
