I have IDC connectors from 4 position to 12 I think, for me in Canada anyway, waiting a week or two weeks for a part sucks.
Grab a mix bag of rubbers, one flipper coil, one sling coil maybe. Extra bulbs, there’s a fantastic multi pack of pin screws/correct size everything/misc. that Marco sells. Plungers, coil stop
I have a couple containers full of totally randoms.
I also broke down a destroyed pinbot, I have ALL the mechs and such to scab off for any of my Williams/Bally pins
Spare yoke for pop bumpers.
