I just picked up a 59Ab flatty from a 1946 Ford. What years should I be looking for when it comes to transmissions? I like the 3 speeds with the shift lever coming out of the top of the tranny. I just saw a 46 transmission on Ebay and it had the linkage on the side, that's not what I want. I'm hoping some of you seasoned geezers can help me out, thanks.
