Old lady clutch pedal

Hey, I just performed this exact modification. I have a 360 in my '65 Cuda with a 4-speed OD gearbox and a Centerforce clutch. I had the exact same problem you have with adjustment. The throwout bearing was always riding the clutch fingers. So I cut and welded the top bar to extended the length between the pivots to exactly six inches. There's a Mopar Muscle article here:

I ditched the large overhead spring and installed a small return spring between the fork and bellhousing.

It works quite well. It allowed to *just* be able to adjust the throwout bearing clearance so it wasn't making contact with the clutch fingers. It did make the pedal a touch harder to push, but not by huge amounts. In the future I intend to go to a hydraulic clutch just because I dislike the heavy clutch pedal so much.

Good luck!
