What do I need to change in the transfer case of a 3 speed transfer case to accept the 4 speed trans on a 1974 FJ40?

Also check out Coolerman's write up !Oy: Coolermans 1971 FJ40 Build and Kurt @ Cruiser Outfitters's write-up. These were very helpful as I work through my conversion (in-progress). Between those and search on Mud, you're pretty much covered.

P.S. Plug for Cruiser Outfitters for the transition gear & bearing you'll need.
