Ended up grabbing a few of these:
They are just a hair long, but I am able to just remove the shim from between the clutch and the bell. There's a wee bit of clutch bell end play, but it's no where near as shit as it was with the bad bushing. Neat! If it ends up not lasting, I'll drop a 17mm ID shim in there to lessen the play. I think it'll be ok unless i start pushing crazy rpms.
The clutch shoes are the exact same as a minarelli V1. V1 springs fit as well. also neat! The rivets in the clutch are more beefy than a v1, so we'll see if it explodes.
I can't tell if the clutch bell is just out of round or off center, but my mind leads to off-center. These things are rather poor quality. Whatever, still works. Maybe a v1 bell can drop in? Who knows.
