My truck is down for a few more days (clutch, tranny rebuild, and radiator rebuild) and I decided to undergo a project. I hate the bulky mack shifter and the up/down split instead of the normal forward/back shift of the eaton. I bought a new eaton fuller A-6918 shifter friday, and the only differences I've found is the mack uses a 7/16 thread at the top of the stick where the eaton uses a 1/2 thread. Each uses four air ports, however a couple are labled differently. Has anyone done this swap before?
