I stumbled on to a Columbia in a 41 Ford that I bought for the juice brakes for my 29 roadster project. It was really a bonus! I've checked it out somewhat and seems to work fine,(one wheel jacked up, and manually shifting the od lever) I'm trying to figure out now how to shorten the tube and ds to fit the back of my '32 B tranny. I've never shortened one so any advice would be helpful.
