Help- 1935-1936 Ford 3.54 gears in a 33-34 rear end?

[Chris]

I know you can do it, my question is how? I have two sets of original Ford 3.54 (39-11) gears from a 35-36 rear end, and I want to put them each in my 33 pickup and my 34 roadster. Both are the late 33-34 rear ends with the "star" shaped end on the torque tube. What is the difference, and what does it take to make them work? Any help would be great!
