Gary,
Most guys don't know what they are. I called a wrecker asking if he had a brownie, said he wasn't sure so I drove out and he showed me a 2 speed rear end. I bought some other parts and there on the ground in his transmission was a 5831A. He had no idea what it was. My point is you need to go and look. Find some truck wreckers and look under the bigger trucks and in the transmission piles. I bought the brownie and would now like to find the shifting tower. Good luck.
