Hi Chris,
I can help you with the W/P wig wag. Is this pertaining to the '51 Kenmore that you posted pictures of? I had a '53 that I junked because it was in such bad shape. I'm pretty sure that the wig-wag is mounted to the gear stud of the tranny by a 5/16 hex head screw. You just have to remove the screw, then remove the 4 wires from the solenoids and rock the wig wag back and forth while lifting off the stud. Had I known, I would have saved the wig-wag from the '53 Kenmore. NEVER thought anyonbe else would need one.
You can email me if you need anything further.
John
