I pulled a good looking transmission (will have to open it up) from a 55 Ford wagon. This transmission had been installed sometime ago, but it was not original to the car. The wagon originally came with a Fordo. I could see where some rigging went on in places. Anyhow, the trans has a side cover and I can see AB5 and 7222R I think the tailshaft has AB7531. It does resemble a T86, but I have not closely inspected everything. The entire transmission was painted a light color of blue...I assume original.
