Thanks gentlemen...I was leaning toward a bushing anyway for the "less moving parts" factor but figured that there was a reason that someone would use a bearing instead.  
Oddly, it was showing up as a special order item.  Summit to the rescue.  

Thanks!

A pilot bushing is less prone to wear and tear than a bearing and works well with YBF. Pioneer PB-50-B is part number. Be aware your flywheel could be either 10 or 11 inches.

Like Charlie, my vote goes for the bushing rather than the bearing.  I have had a couple of instances in the past where the pilot bearings were an issue and switching back to the bronze bushings solved those issues.

Here are some additional links on this site discussing pilot bearings versus bushings.

Bushings, because they don't run out of grease or oil and dry up and destroy the input shaft.  Been there.



Lawrenceville, GA

Getting ready to FINALLY start a transmission swap (if it fits) next weekend and figured I'd start getting some parts on hand.  The engine is a '59 292- should I pick up a new pilot bushing or bearing (which do you prefer) and does anyone have a part number?
Also, not sure what diameter clutch to get for what I assume is a stock flywheel.  The car is a 1930 Model A.
