Are all pilot bushings bronze?

Ok.....after a sleepless night (I'm a very anxious person by nature) I have decided to order a Mcloed oilite bronze pilot bushing, ordered the tools needed to check bellhousing alignment within .003, and run it. The fact that the O.D. of the input shaft is unaltered gives me confidence it will ride fine in the new bushing (and the fact the I.D. of the old bushing is un-scored. The freeplay in the input shaft is minimal, not sure how to measure that play.....

There is a reason major clutch manufacturers here send you a new bearing when you install a clutch. Ask Steve at Monster, Jason at TDP, etc. These guys know bearings are for drivers and bushings are for racers who don't mind pulling a trans every 10k.
OP, I hope it works for you. My personal experience is that a bushing will fail in about 8-10K of regular driving. The good news is that, if it does fail, all it is is a pain in the butt to pull the trans and switch to a bearing.

Well one good thing is its not a daily driver, it maybe comes out once or twice a week to run to the gym 1 mile away. Trip to a car show or weekend drive with the old lady will be the only real miles.

8-10k?? You must have been using a cheap bushing. An oiled bronze bushing will serve you for as long as the clutch. Bearings are a b*tch to get in and if you beat on them too much, they're junk. Also, the tolerances are horrible since most if not all are chinese. Bushings are failsafe. even if a bushing does wear out and you keep driving, your input shaft won't get destroyed like a bearing. they went to bearings because believe it or not, they are cheaper to manufacture because of the high copper (bronze) prices.
I'm with you on this one.
Bushings have been used for decades. Never had one fail before the clutch and I just change them when a new clutch goes in. I don't think I've ever got less than 60K miles on a clutch either for a DD.
