Stuart, I'm wanting to switch over to roller bearings but need numbers to order them from my local parts supply (figure they'll be lots cheaper then thru one of the catalogs)..are the the numbers you gave good for over-the-counter ordering?? Are those front or rear??
Inner seal: National #6064
Inner bearing and race: MBS #909052R
Outer race: Timken #LM11919
Outer bearing: Timken #LM11949
