[37 Coupe]

It is the original 1955 Ford Thunderbird overdrive trans. I will measure tomorrow but pretty sure the NOS one is the same as the one I removed. I just wish I could find a picture or illustration of what I am attaching the plunger tang to that a 90 degree turn is necessary to install or remove. I also have to replace the little oil seal that plunger enters trans case,I bet that is where all the gear lube ran out over forty years sitting,no seal rubber is left.
