I'm getting ready to pull the original 85hp flathead from my '39 Ford coupe along with the original 3 spd with it's worn out second gear synchro and replace it with a '65 327 sbc and 200R4. I will pull the torque tube and replace the rear end attachment with a Speedway 6 spline U joint. Anyone with experience modifying the X member center to fit the automatic tranny? Any suggestions would be appreciated. I am particularly interested in how you solved the kick down cable, speedometer cable, shift lever issues. I would like to use a Gennie floor shifter.
