Just dropped the tranny from my '51, 3spd on column, with torque tube. Engine is a '50 216. I will swap to a T5 but am curious as to what i have. The link below takes you to my pics - first 4.

When looking at the casting code it looks to me like a "581615" but I cannot find that code. I find a "5 9 1615" which is a HD 3 speed. The H239 manuf code is also hard to find as i think it should have 2 letters followed by the manuf date. I have not taken the bellhousing down yet. Any insights?
