I don't know why Petronix wouldn't work unless it has something to do with the fact that your distributor is mechanical, not vacuum advance. To answer your question, 1937 and later 120 distributors will nearly interchange, problem is, you need to change the gear on your oil pump to the thicker distributor drive "shim". Not a big problem, I'd be happy to give you one if you want to buy a later distributor to go with it....I've got a couple 38-39 120 distributors, etc.
