It;s really only 8 ratios but still fun. It's done with the Saganaw 4 speed and the OD from a 3 speed saganaw of the same vintage. They used the same case. You have to use the main shaft from the 3 speed and sliders from the 4 speed. Lots of "how tos" on the net. The older Borg ODs wont bolt up. Saganaw 3 speed ODs are getting hard to find and the special solenoid used only in the Saganaw set up is even harder. NEVER throw away a broken OD solenoid. They can be fixed! It wouldn't help in a racing application because of strength and the time it takes the OD to shift but for fun on the street it is a fun combo. I'm going to put one behind the 4 cylinder in my roadster. I have often thought of using the plentiful Borg ODs for other applications as a stand alone. It would take modified front cover and a yoke.
