madd thanks to Mattback for the clutch. i just put a sr clutch in my twin cam KA. if you can find a decent used sr clutch cheap all you need to do to put it in your ka is have the flywheel erdrilled for the sr clutch bolt pattern. and i got a guy with a machine shop that did it for me for $90. so the hell with spending $300+ for a ka clutch when you know you'll end up swapping to an sr anyway so just buy an sr clutch and put it in your ka until you get your sr.
