Clutch rust

[the_goat_man]

Ok so I picked up a 66 c10 that has a 350 and a m22 4 speed. And the clutch that is in it is a three finger. I just removed it and the clutch fingers where seized in place. I put pb blaster on them and worked them and 2out of the 3 work great. The one does not release all tge way it leaves like 1/8 sill to travel. I don't have the cash right now to buy a new clutch. Is there a way to clean it real good?? It also has an aluminum fly wheel the clutch disk is in freak shape. The truck may not have even been driven on it. Is there any think I can soake the springs and fingers in to get it. To move better thanks
