Technical 1951 Mercury 16 Spline Transmission Yoke

I am having a devil of a time finding this part. The driveshaft in my '51 Merc Coupe dissolved a long time ago, and I guess took the yoke with it when it was removed. Can anyone help me find one? I have tried:

Northern Drivetrain
Mako Driveshafts
Denny's Driveshaft

Even bought this little beauty but it didn't work: https://www.fordbarn.com/forum/showthread.php?t=326915&highlight=yoke

I appreciate any assistance.

 

'55 to '62 , 16 spline Chevy yoke will fit, BUT, has a Spicer joint not a mechanics joint.

 

Shoeboxcentral sells new ones.
