Hi Jerry,

Thanks for the info. It turns out that the fork was fine, so the pressure plate/throwout bearing was my next guess.

Unless the bolts to the pressure plate can be torqued down too tight (can they?) the only logical thought is that the clutch cover is not as tall as the old one, or that (as you say) the throwout bearing is shorter. Or both. I still have the old throwout bearing just in case, but would rather install a new one.

I also found a crack in my tranny housing :-(

My mechanic calls it an oil leak... I call it my truck's 'self-lubricating chassis' feature.
