Bellhousing clutch pivot setup...?

[drudis]

According to the article on www.mustangworks.com :
"...Also, lay a straight edge across the face of the bellhousing and measure the distance to the tip of the clutch pivot stud. Compare this to your stock bellhousing or you may run into problems. On my particular bellhousing there was a 3/4" height difference that caused the clutch fork to apply constant pressure to the throwout bearing and it rode on the pressure plate. The cause was found to be the wrong size thread in the bellhousing for the clutch ball pivot and their adjustable pivot would not work. The solution was to buy a clutch pivot from Ford that was 1/2" shorter (part number D9BZ-7B602-A) and also mill the stud boss down an additional 1/4" in the bellhousing. In most instances however, you should be able to remove the factory ball pivot from your existing bellhousing and install it into the new blowcan. "


QUESTION: WHAT IS THE CORRECT PIVOT STUD STOCK HEIGHT?


I am getting ready to re-install the bellhousing on my TKO.

I re-read the Mustangworks article, and have one dimention that is not sure of the height. That being the height of the pivot stud:

Do you have this measurement? (what is it)

I measured (the opposite) from the bottom outter edge to the top of the stud, and got 83mm. Do you know if thats right?

I assume it makes a difference with the different bellhousing heights (aluminum vs steel)

that this height should be from the BLOCK-to-pivotstud WITH the spacer-shim included
( not the TRANNY-to-pivotstud). Do you know this height? (I dont have the stocker to compare it to).
