Clutch Fork Geometry Woes...

It was supposed to be a Stock Upgrade for this Bell. It's only a Half inch bigger than the one that came out and came with special bolts to use with the Stock Flywheel.
So, it's the Wrong Clutch then???
Didn't I get this clutch from you Don? @65 Dartman after Brewers Sold Out of them?
It was for this Set-Up or am I mistaken? (273 to 9 1/2" Bell to A833)
