I think they discontinued anco 41-03 wiper arm, maybe anco 41-02 is universal substitute?

41-02 is 10-13.5”. 41-03 is 14-19”

Need a set as well for my 71. The Mopar parts places want a silly 125-150 for a set. Has anyone found any that work? Maybe a modern style one that you can prop up on its own to allow easy window cleaning.

I used the Anco universal arm and discarded the flat shaft with the funky universal end. Then I disassembled a stock Mopar arm and inserted the flat stock part into the universal base. The Anco color doesn't look right, but it isn't noticeable if you aren't looking for it.
