Can anyone verify if all 1941 thru 1946 Chevrolet trucks used the same bell housing, for 3speed and 4speed transmissions? Does anyone know the model number for these bell housings?

I’m trying to swap from a 4spd to a 3spd and just want to make sure I have all the correct parts.

I’ve researched and found bell housing #838533 AND 839257. Does anyone know which one is correct AND if they are the same for 3spd or 4spd?


Thanks for your help
