I got a used williams unit and I popped the shell. The leads to the reverse board were rubbing on the flywheel. My question, the reverse board was mounted using the hole on the left which is surrounded by a silver coating. Can I use the adjacent hole (the right hole) to mount which would move the board away from the motor.

Yes, either hole is fine for mounting.

Normally the reversing board is the one mounted flat. Makes me wonder what you have, two reversing boards? Or does one do something else? Anyone know?

I'm sorry but that is clearly a blue relays early Williams reverse board. I probably have touched a dozen of them.

I've seen many Williams reverse boards mounted vertically, they use a small "L" shaped bracket to attach to the mounting hole and then the bracket connects to the frame.
The other board is a sound board, I believe just a horn.
Again, to back up the original question:

Since the new modern boards of Williams are somewhat similar- 2 rectifiers, 2 relays, much of the circuit is the same or very close.

3: If not using bracket go to next step. Place plastic washer onto long bolt. Insert bolt into hole 4 or 5 (Figure 1) on
the component side of the circuit board
Again, either hole is considered perfectly acceptable.
