yes, IT WILL WORK:D
taken from Novak site:
The T90 used from 1946 to 1962 with the L and F-head four-cylinder engines is designated as the T90A1. These versions all feature top shifters, a 7" input shaft (stick-out length) with 15/16" x 10 splines and a felt-sealed front bearing retainer assembly. The input shaft has an 18 tooth, helically cut input gear. The cluster gear has a 33 tooth driven gear, resulting in a 2.79:1 first gear and a 1.55:1 second gear.
....The M38 and M38A1 Jeeps have basically the same T90 3 speed transmission as CJ's but they have two plugs that screw into the front of the shifter cover rail bores that protrude far enough to hit the back face of some conversion applications. They may have to be modifed and plugged as appropriate.

Also the M38/M38A1 shifter top has an integral rubber boot and the CJ tranny requires a separate boot for the shift cane. If your military tranny shift cover is ok you should put it on the civvy T90.

If it's cheap or free get it and look into it. Maybe something easy to fix.
