I've picked up a NOS OBX that's been gone through by TU and I'm getting a ring gear spacer made. What I'm having trouble finding is what bearings I need to use on each end.

The passenger side seems to be the same as stock a413 *I think*, but the driver side is what I'm having trouble with. Since I have a larger bearing retainer with my later model transmission(s), I'd like to use an equivalent larger OD bearing, but it looks like the OBX is smaller on the drivers end compared to my stock large bearing diff.

Is there a bearing that anyone knows of that is normally used?
