When I overhauled the transmission, I remember the casting numbers and gear teeth matching a 1964 - 4 spd, and the side - shifter plate being the latter model, reinforced plate with '64 era shifter forks.
At some point, I'd like to entertain different rear end gears. For now, I appreciate the 1st gear synchro when turning corners in town and will settle with shifting into 3rd when I approach a hill under 60 MPH. With my foot in it, 2nd to 3rd can be at 55 MPH.
