I am in the process of putting a b15 clutch in my b13. Is the b15 disk AND pressure plate compatable w/the b13 tranny? I have the tranny on the motor and there is considerable clutch arm play. Should I use a b13 PP with the b15 disk or use the whole assembly? I have a new b13 PP, should I install it instead w/ the b15 disk and shitcan the b15 PP? My concern is the throw out bearing coming off the shaft inside the tranny. There is almost too much clutch arm movement. Anyone running a complete b15 clutch assembly on a cable B13 tranny without problems? I need immediate help. TIA.

I just put a B15 disc with B13 pressure plate in my car 5k miles ago. It had about the same arm movement as a whole B13 setup. Nothing I considered too much.
