1932 rear end parts question

[DennisV]

I have a 1932 rear end round flange that was behind a 4 cilinder engine (now with flathead v8) 4.11
I want to change to 3.54 and i understand that the ring and pinion is the same as model A but what about the bearings race and seals ?
Do have to order only model A parts ?
Don't want to spent money on wrong parts.
