Any opinions on which pilot bearing to use? An original roller -or- bronze pilot bearing for a street use stock 400 with M21 3:55 posi rear?

Thanks-

BCA7109 ball bearing pilot.

Run to Rund

Or, Dorman 690-023 bronze. Ball bearing is better if alignment is perfect and it doesn't run dry. Bronze won't last as long (but plenty long enough these days) but also won't roach the input nose if something goes bad.
