For what it's worth, I posted the STL files for the leg bracket adapters and BoP face plate brackets on my github repo.
Just a refresher, we created the leg adapter plates to fill the gap between the "new style" Williams leg brackets and the corner gussets. When you remove the smaller plate and add the new style, the adapter sits between the gusset and the new bracket.
The face plate brackets are designed to be used with the new, CPR replacement face plates for the Bride's head. The old face plates had metal brackets screwed to the back to keep the pinballs from falling through the holes. The new face plates not only do not have mounting screw holes for the metal brackets, but also the holes are bigger and not beveled. This leads to balls falling right through, and if you try to use the old metal plates, the balls wobble or roll to the center. The new plates are meant to be two-sided taped or glued to the back of the new plates, and they hold the balls perfectly.
