I looked around when I got mine. I was working at Car Quest at the time. The outer bearings and races are a standard tapered roller bearing set. The inners are just like the later tapered roller inners except there is a built in spacer. At the time I didn't have the tools to play with it. I think a standard Timken or other bearing with a spacer could be made to work. I think the seal is stock. I'd have to look at it all again. I think the price is a rip off except sometimes you just have to pay more just to have a low demand part available.
