Bellhousing pivot ball adjustment
My pivot ball is on the passenger side and the throwout bearing sits in the middle of the clutch fork. Is it possible to affect the clutch arm travel if the pivot ball is misadjusted? What is the ideal relationship between the clutch arm and the throwout bearing when the pivot ball is properly adjusted?

That's a good question and I'd be interested in the answer from the professionals. It's hard to explain, but I adjusted mine so that when the hydraulic cylinder is half-way through it's arc, the clutch fork is parallel with the ball. That way, it swings the same distance forward as back.
I'm not sure it really matters. It can be adjusted to just about any point by changing up the height of the pivot ball or adjusting the spacers where the hydraulic cylinder connects to the clutch fork.

Absolutly. The height of the pivot ball is pretty important. For the standard Mustang clutch assembly and arm, use the stock Ford non-adjustable ball stud; it's the perfect height. I can't remember the exact measurement, though.

The ford non adjustable is fine if you are using the stock Ford T5 bellhousing.
If you are using an aftermarket scattershield/bellhousing the adjustable one might be the best.

I don't remember if mine is adjustable or not. Can anyone tell me if the clutch fork starts out angled away from the flywheel and ends up parallel with it when fully depressed... or vice-versa... or something else?

Go to www.hurst-drivelines.com In the blue box on the left go to technical help, then click on technical articles, from there click on clutch linkage installation and adjustment. Yes, it is for a non-Ford product but they are all the same. You will see the angle is 5-7 degress, to the front of the car for the clutch fork. This angle is a result of the lenght of the pivot. Lakewood sell adjustable pivots as mentioned in the article. This six page article should answer all the questions you ever had about throwout bearings and clutch forks.
