My son needs two bearings actually... for his build-off 2013 entry. He needs two bearings for his back axle with a 3/4 inside diameter with a 1-5/8 outside diameter AND it needs a flange. Ive checked MFGsupply.com and the OldMiniBikes, is there any other place I could try that might have a set of bearings on a 14y/o's budget? Googling bearing sizes returns lots of irrelevant results. Thanks!
