z-bar question

My recollection of the rod from the pedal to the z-bar on my Barracuda is that it's not straight. The ball stud that goes through the sub frame has a fixed location in side the z-bar. The spring pin that warps the z-bar fits into a groove in the two piece plastic bushing to locate the z-bar (when this pin is locked in the rod is centered in the hole in the fire wall). The ball stud on the bell housing side is allowed to slide inside the z-bar to compensate for engine mostion.

When I swapped from a \6 to a 360 I used the \6 z-bar (cut about 1.5" off the bellhousing side) and used the \6 fork in the sb bell housing. Everything seem to line up correctely but I have an issue that when the clutch is adjusted for 1-2" of pedal play and the pedal is on the floor something inside the bell housing touches (fork contacts pressure plate of fingers touch disk). When adjusted so this doesn't happen the pedal does not return all the way (the over center spring holds it on the far side).

I will be sorting this out this winter with either a proper sb z-bar or clutch fork.
