hi ryan,, almost always,, the bearings you remove will have some sort of # on them, and a manufacturer.. we have some stores around here called, "berry bearings" just give them the info, and they should be able to get an exact or similar bearing..
^ Exactly. Every bearing will have a number on it, if the company who sold it to you didnt' erase it. Try www.bocabearings.com and you should be good to go.
