Overdrive

[SirWinston]

I might know the answer to my own question, but looking for more advise. I wanna drop in an overdrive on my 1960 Willys truck t-90/dana 18. Right now its running with the 11/8th intermediate gear shaft, I have a 11/4 shaft dana 18. Which transfer case would hold up better with the new warn Overdrive system? Thanks for the help.

Either will do just fine. Remember when in overdrive, torque is reduced by the gear ratio.
