Trying to find Wiper output arm 68-72

[lovemycbx]

Part number 17A436 is all I can dig up but since ford used the part number with additional designations over the years it's not much help. The wiper motor output arm in my 71' F-250 has wallowed out and I' trying to find a replacement. I'm digging in to the wipers and adding an intermittent module and trying to get the whole wiper system fully ready to make it back up in to the snow. I picked up one for a 71 mustang on ebay and it's a no go. The fact that it's such a rarely removed or damaged part isn't helping much. As I understand it the same part should be used from 68-72 please let me know if anyone has one of these and thanks for your time, Ryan.

*Update*

I found a old burnt out motor with arm attached on Ebay I just grabbed.
