Clutch fork. I bought one off one of the guys on the forum and got the pivot from an online source (don't have my receipt file handy, so can't remember who). Dialing in the bellhousing was pretty tricky, so be sure to make adjustments a tiny bit at a time or you'll end up starting over. Also, my bellhousing didn't clear my beefy aftermarket starter. AND it didn't clear my headers. AND... we welded some bits on it to simplify the dial in and for our improvised clutch linkage. Keep in mind that if you want to take yours to the track, you'll have a hard time resolving those kinds of issues, since you can't grind or weld on the bellhousing and meet NHRA reqs (I ground and welded the bejesus out of mine). It was a real beast for my application, but at least I won't have any shrapnel in my foot. Plus I'm sure plenty of people had no trouble at all.
