throwout bearing to fingers gap?

My memory is that a Borg and Beck clutch needs about .080 plate departure clearance, while diaphragm only needs (and should be limited to) .035. However, haven't been able to confirm that online, and this web site

The Novak Guide to Clutches, Linkages & Bellhousings for Jeep® Conversions

says different:

As stated above, the diaphragm type clutch takes slightly less travel to release and requires about .030 total air gap when released. The coil spring type [i.e., Borg & Beck] requires about .040 to .050 total air gap when released. Air gap is the clearance between the clutch disc, flywheel, and pressure plate with the clutch released. A total air gap of .050 will measure .025 between each side of the disc.

Too little departure clearance and your clutch will not fully disengage when you push the pedal all the way down. Too much departure clearance and the fingers on a Borg & Beck clutch will hit the clutch disc, or, on a diaphragm clutch, you'll over compress the spring and it may not come back

If you're running a non-stock clutch, I'd get the departure gap where it's supposed to be and let the clutch pedal fall where it may. If you don't like a low pedal, you can always modify the clutch stop (above the clutch pedal) or even bolt something to the floor under the pedal to reduce travel, which will put the pedal higher when you adjust for correct departure clearance.

As for clearance between the throwout bearing and whatever it pushes against when clutch is disengaged, all you need is enough clearance that it doesn't touch when the clutch is engaged - keeping in mind that whatever clearance you have there will decrease as the clutch disc wears.
