I did this change in 1961 but have forgot if the original drive line had to be modified. I pulled the good three speed out while doing some clutch work at the Pearl Harbor Submarine Base hobby shop and while I had the tranny out decided to dissassemble and check it out it was in perfect condition. I placed all the parts on a pc. of plywood in the back seat over a day when the shop was closed when I returnedsomeone had stole my good parts and replaced with there old broken ones, so I found a overdrive unit ($35) that worked well I used a spring loaded toggle to momentarily kill engine for down shift passing gear, I even had OD in first and reverse gear. I am considering putting one in my new 50 Ford.
