I have had good results using OE style bronze pilot bushings in FE applications using organic disc material, but they will not live with a sintered iron drag race clutch, the abrasive clutch dust eats the soft material in very short order. On my Fairmont, with Fe engines, and a sintered iron clutch, I also use a 6303 ball bearing, but preventing them from falling out can be a challenge . The hard outer section would be great is it was a thou or 2 larger OD, as they don`t fit as tight as I like, at least on the OE Ford crankshafts I use, also the ball bearing outer section is thicker than the hole in the crank, so it hangs out a bit. Also the fit of the input shafts pilot tip is nice and snug, so combined with the slightly smallish OD, I often experience that the bearing pulls out of the crankshaft when removing the transmission. I had tried various Loctite styles, which helped some, but still usually allow the bearing to come out during trans removal. About 15 years ago, I had used a Ford needle bearing pilot bearing, that had a powdered metal outer section. Unbeknownst to me, the pilot walked out, and during a dragstrip pass, my clutch disc ripped out the hub around the rivited clutch hub (McLeod Soft Lok, sintered iron , solid hub), and my guess is that the pilot had walked out some time earlier, and that allowed the input to move up and down enough that the disc cracked around the hub, until it broke free. When I stabbed the clutch pedal, the disc dropped down enough to grab the inside of the Lakewood scattershield, and carve deep grooves inside, and the pieces flying around put large dents in the bellhousing, fold over the pressure plate flange, and snap off the starter nose. When I attempted to remove the transmission, it pulled back about 3/4", and jammed up, as the front bearing retainer of the transmission was flared out enough from the moving input shaft, that the throw out bearing would not slide over the bulge. The bellhousing, clutch and flywheel, starter motor, clutch fork, as well as the Jericos front bearing retainer and front bearing were all destroyed. All because of an inexpensive pilot bearing.
