Looking for some help. I am having a hard time finding the part number for Timken bearings and seals for a 86' 442 rear, both axle bearings. (8.5") I do not need the repair bearing / seal. I don't want junk bearing part numbers, please, Timken or equivalent. It seems most part catalogs are only offering the 7.5 rear, not the 8.5 I have.
