We have a flat bed bale hauling trailer built on a 1951 Chevrolet 1 1/2 or 2 ton truck frame and can not find front wheel bearings anywhere for it. They are a timpken roller bearing with barrel shaped rollers. No one can cross the old numbers. Does anyone have a source for parts, maybe a chevrolet truck restoration business. Hate to junk the trailer, its only 52 years old! Thanks.
