A Brownie is an aux. trans, works fine w/ 420, etc. Nice to have the OD on level and downhill, direct, 3rd. direct on hills. I drove across S. Iowa w/ 302, 280V(direct), Brownie, lots of useful gears.

Shift linkages for a Brownie are easily made of EMT or water pipe, don't worry about that, just make sure to get the shifter itself.
