I have a stock 1963 F-100 Unibody with standard 3-speed on the column. Wondering if anyone has swapped out the stock tranny for one with overdrive? What if any interchange with simple bolt-on fitment with Ford trucks of that year?

 

A little bump
Might ask this same question in the main 61 - 66 truck area as I am sure more people look in that area than in here.
You might also want to post up what motor you have, model of trany, rear gear ratio and lastly tire size.
All of this information will help pick what way to add overdrive to your truck.
