That Timken site is awesome! There's literally everything you need there to cross over a bearing.
For a tapered outer wheel bearing I have a 1280/1220 combo. The dimensions are identical the b45 outer ball bearing.
For the inner b46 I get:
27880/27820 and 27881/27820 combo. Like I said before, all you need is a 9/32" thick 2" ODx 1.5 ID thrust bushing to make them work.
These bearings are already in production too. The 27880 was used on 46-52 Fords and 87-91 Ferrari's. The 277881 was used by IH from 55-72.
It's too bad I already bought the MBS.
