(2) Also, not sure which parking brake arm is the pass. side and which is the drivers side? Does the bottom "U" shaped bend that holds the cable on the pass. side rear go in toward the backing plate or does it face out?
Luckily for me I did not have to get into the park brake on my 50.

That may be why I'm not sure about the wavy washer or the arm position.

maybe someone will chime in with some help
