according to my Oldsmobile factory parts manual part # 504740 flange,universal joint (axle end) is the same for 1940 through 1947.
see i found a nos one and it says it is for 47-50ish....but looks dead on to mine......i just need to know for sure on buying the new one that it is right thanks, jim
you might be able to make that one work,if you can't find anything else. have you removed the old one yet? it might just need a spacer or something to make it work.
