Pilot bearing- bearing? bushing? kevlar?

[Deezul1]

What works the best when there is no damage or problems involved? In 40 years I have never seen an oilite bronze bushing give trouble so thats my 1st choice. How about anyone else, whats your experience here. No opinions please just real life experience. I am mostly concerned with 2nd gen trucks.

I have one that you haven't mentioned. My flywheel has a big roller bearing, same as what's used in a Kenworth, courtesy of Dave Mitchell and Co. at Enterprise Engine. It has lasted over 40,000 miles. I'm upgrading my clutch later this year, so we'll see how it's lasted. I may just get a new one pressed in there anyway. The flywheel has to be machined for it to fit. I'm not the only one out in TDR-land that has one.
