Haven't seen a J-112 but a J-933 is the correct wrench for the post-war 3sp clutch (input) shaft. I just tried it on a 1940 trans and the fit is the same. Look at the pics. 1/8" thick and 1-5/8" jaws. I think the bend in the handle is probably irrelevant, but it does make for better balance. May be why you can't find a 112, it was probably superceded by the 933. Need a press. It's a press fit. Make sure you re-stake the nut when you put it back on. Make sure the snap ring fits the recess... may have to use the old snap ring. I did.
