I need to replace the bearings in my alternator. Since I do not have a backup alt, I need to assemble all of the parts before I do the fix. What I specifically need to know is either the dimensions or the part numbers of the bearings (Timken?) and if there is anything else I should replace while I have the thing apart, such as brushes or the regulator. TIA, Charley DePenning '83 5kT
