Establishing same PN for both pedals.
Discussion: The Factory and replacements have a spiral "split" on the inner sleeve portion of the bushings, most brass-bronze bushing are not split. Was this feature for lubricant retention or to allow for tolerance variations on the parts to accommodate "slop" and aide assembly.
This is a good hidden upgrade.
