When I installed the QT, I eyeballed the pivot geometry from the LW and tried to replicate. I took a good look at the clutch fork. There are a few different forks out there. I converted the car to a stick back in the 80's and used swap meet parts. I broke the outboard portion of the clutch fork off way back when so you can see how we boxed it in and added a support behind the round flange. Then it occurred to me that maybe the clutch fork had the wrong dimensions ... maybe the distance between where the fork hit the TO bearing and where the pivot recess in the fork was different than the pivot to input shaft centerline. I also noticed that the two different pivot brackets supplied with the QT bell had a different "offset". Humm ... could there be more to this than I thought?
