81ish pantera primary clutch?

just sold this old pantera to a guy yesterday. i am pretty sure it was an 81. i got it from a guy for doing some work. i was going to get it going just to piss around with, but never had time. i wasn't aware of it, but he said that he got it home and was looking at it. the movable sheave has a crack in it. he said it goes all the way down to the shaft.

i feel bad, never meant to screw somebody over. can anybody lead me in the direction of some used parts? i looked them up on a microfische. the whole clutch is 0225-149. the stationary sheave is 0146-499. and the movable sheave is 0146-204.
