73 Barracuda 3 speed wiper motor crank part number?

Does anyone happen to know the correct part number for the wiper motor crank (arm that connects the wiper motor and linkage)? I sent my original one in to have it restored with the wiper motor. I got the wiper motor back but did not get the crank back! Now it seems my original wiper motor crank is MIA and can not be found.

3431518 is the part number. I have some crank arms but I`m not sure if I have that part number. Let me know and I will take a look for it.

I think the company that did the wiper motor resto has the part on its way to me. If not I will let you know and see if you have one. Thanks
