No ACL and less than 400 hp, sell me on a clutch

I would change to a diaphragm type clutch. Their design has come a very long way. The good ones, anyway. That will be MUCH easier on your whole leg and hip as they are a lot easier to operate. Of course they require the large over center spring to be removed, but that's a plus. Look at good quality clutches from Hayes, Zoom and the like. I believe Zoom is still made in the USA.
