I was enjoying a favorite passtime... Wandering the Pick-N-Pull. At the exit, there was a 3 spd trans on a table, marked as from a 32 coupe. It had a second lever over the output shaft that I couldn't identify... Looked like an overdrive lever, but I'm not sure.
Casting numbers are these:
Case: 590532
Shifter Housing (floor shift): 590591 7
Other lever housing: 367950 or 867950?

Is this a 3 spd floor shift with overdrive? It is definitely for a torque tube rear. If it is an OD 3spd, would it bolt to my 49 216?
I know, I shoulda taken a picture with my phone.... I never remember to do that.

Knowledge is a wonderful thing, but ignorance means you don't know you can't do something.
