the clutch might well be for a ka24, ive been trying to think what else it could have been for, and that sounds very possible?? heres a couple of pics of it, the first one its under a standard s12 cover, flush at the top to show its sliightly bigger, and the second is of it on a s12 flywheel, the 2 top dowels are lined up and that pushes the other one out this much.....so i might have to try some careful slotting on all the holes? i was just gonna do this before, but dident want to unbalance the fly.....
