Flackmaster, you just might be my hero. I'll have to double check on Monday when I can get back to the car, but the info I have on hand is the shaft o.d. is 7/8" (and if I remember correctly has 40 splines?), the o.d. of the bearing should be about 1 1/2", and the depth of the bearing seat in the shift bowl is about 1 1/16". The shift bowl and column sleeve are both round, with the shift lever hole at 12 o'clock and a "dent" at the top of the sleeve behind the bowl in the 2 o'clock position for shift lever clearance. (I have a second column that isn't round, and that bearing is definitely different). The bowl has 330939 cast into the bottom inside it. Not sure if I need the washer too, I'll have to look in the box of parts to see. Thank you :)

Thanks for the pic. I tried Max as well, he didn't have it. Unfortunately, the bearing has no number on it, so I'm stabbing in the dark now...

Does anyone know where I can get a replacement upper column bearing (the one just under the steering wheel) for a '40 120? Or maybe a compatible part (or part#) that will fit? I've checked Kanter and a few others and nobody seems to have one.
