The bell housing ball is 7/8 tall. It is into a 1/2 tall boss on the bell housing. The bearing retainer surface that the bearing slides on is 2 1/4" long with the bearing being 1 3/4" long. That leaves a 1/2 of travel before the bearing protrudes past the retainer. When this is assembled the pressure plate fingers are about where the end of the retainer is... meaning the bearing has to go beyond the retainer to push on the fingers. I am starting to blame my renewed 10"(junk yard)flywheel I have. The disc surface is 1/4 further away from the bearing on it compared with the 9 1/4" recessed flywheel.
I posted some pics with notes below them to assist. http://community.webshots.com/album/86356492fGDxkm


Thanks to all!
