According to Eurospares it's a completely different part number:
3200: 387200388
4200: 185564
Different part number, different price, looks totally different on the diagram.
Other than that: identical

I’m a great believer in if it was made, in can be unmade and made again...
Pushed it apart with a press replaced the Balls ground a few thou of the faces and pushed it back together with new seals. Old school engineering ! Can't be done if there are signs of any pitting in the ball grooves
Hand Brake shoes back from Villiers (the old motorcycle engine company) Relined as new £33.00 the lot!
Good job there are still proper craftsmen out there!!
Seems likely the 3200 rear bearing is shared on Ferrari produced in same years. The new alternate part on eurospares seems to be 'almost the same'.I think it's the same part, also used on several Ferraris apparently! We think It is a generic part that Maserati source in, they remove any casting numbers etc for obvious reasons for all we know these could be fitted to a fork lift or the like!! Borg Transmissions would have sourced the manufacturers eventually but in this instance it was quicker to recon the original unit
