You will need to modify the driveshaft and obtain the column shift linkage rods and components.

I have a friend with a 49 1/2 ton with a 261 and a 57 3spd overdrive. he has the kick down on the gas pedal. I just drove it a few days ago , it sure is nice to drive. the only better way would be a later Saginaw all synchromesh 3spd w/od.
