Yeah, why would anyone want that? If you are going open drive a later 3 speed would be easy and synchro first and can be made to work with the stock shifter. Personally I think the torque tube with 3.55 gears is the way to go….
The main reason for using it is that you don't have to change the bellhousing or get and adapter to fit a Muncie pattern Transmission to the earler small chevy bolt pattern bellhousing . Trucks went to the Muncie pattern in 48 but cars didn't until 55 and 54 and earler motor monts don't jive with 55 and later six cylinder bellhousings as far as I know. .
