I just need an overdrive unit that I can use on a 235 with a Granny 4 speed.
Anyone have any ideas? I have heard of Brownie, but hearing about it and
actually having a solution are two different things.  Friend of mine has a
nice solution for the 3 speeds, but for my 49 3/4 ton with a 4 on the floor,
no luck.
