Thanks Dean. I'm almost certain that the throw-out bearing was fully retracted (it is now, with the tranny out and unless my helper (youngest son) reset it without mentioning it to me...), but will certainly double-check that when we try again. I can't tell you exactly how big the gap was and can't remeasure now since my son is not avail for a couple of days, but from my visual inspections yesterday, I'd guesstimate the gap at about 1.25 - 1.5 inches.
