After re-reading my post, I don't want to give the impression that a NP210 and NP420 trans covers can directly interchange. When I was assisting Marcel rebuilding his 1953 M37, we wanted to replace the cover to tighten up the shift lever play. The cover had one pin so we didn't think anything more about it, we thought it was the NP210 model so we called John at MWM to buy a new cover assembly. John sent us an NP420 assembly so when we took off what we thought was a NP210 cover, things didn't look right. We had a NP210 cover with NP420 forks. Someone had replaced the NP210 forks with NP420 forks and we verified the transmission by the case number. So the cover housing is interchangeable, but you have to install forks for the appropriate transmission. Sorry for any confusion.
