Motor brake switch assembly is B-8306 (it's the blade plus the spacers on it).
Standard operating procedure to rebuild the score motors as far as I'm concerned...
(And the later games have a hand-written date on the top of the score motor itself, which is kinda cool to see when a particular game was actually built.)
Also a good opportunity to oil the pads, top and bottom.
Add back some SuperLube on the dog bone switches, and other switches that hit cam posts, and these are ready for another 30 years.
