Thought I would close this out. Best thing to do would be to use a press to straighten the retainer and then grind out any burrs. But one of the retainers was lost. I used some standard machine bushings, 2.5 in OD x 1.75 in ID x 14 ga. Was a little smaller OD (0.03 in) and larger diameter hole (1/8 in) and a little thicker (14 ga vs 16 ga). But the axles and c-clips, bearings and seals all went in just fine. The bushing has enough lip to grab when removing the bearing next time, so all is fine. Thanks
