The clutch works just like it should, no other problems besides the one with the throwout bearing.
There is no interference between the fork and the cutout in the bellhousing.I checked the whole setup several times from under the car while I had a friend depress the clutch pedal.
I found one interesting thing on Davids homepage:
he sells this part as a "Bellhousing clutch fork pivot for
1968 and newer forks"
This is the kind of pivot I have installed.
My transmission is the older- style 1964 narrow housing Toploader. Chances are the fork is also pre- '68.
What pivot was used before 1968?
