Mike - it's currently seated without any shims, all measurements confirmed this ... as did the final fitting. With the bearing fully retracted, there's 0.150-0.200" of space between the bearing face and the springs, with it fully engaged it pushes the springs in, and clearly dis-engages the clutch. This was tested before I bolted everything together: put the transmission in 4th (1:1 ratio, btw) and clutch pedal out (clutch engaged), I could not turn the driveshaft by hand... clutch pedal in, everything disengaged, still in 4th, I could turn the driveshaft by hand.

I drilled a 1.5" window in the bell-housing (necessary to easily adjust the bearing onto its guide) and can visually see the engagement/dis-engagement too.

So, the high pedal is itself just how it is. You can buy a pedal adjuster which can move whereabouts in the pedal it bites, but I'm fine with it as-is.
