Thanks Gp. I see online info about a BW T85N 3 speed and a Muncie 319 with a BW R10K overdrive add on. I see no sources for either. I have the original non overdrive 3 speed. Overdrive would be essential to keep a 3 speed. The existing tranny case stamp is not fully legible. Where does one source a strong 3 speed with overdrive?
