Quoted from MVCO:So, it sounds like I should avoid anything from 1984 and later as it would have the hinged head?
IMHO if you are comfortable removing a classic Bally or Stern head then I would not avoid the hinged Williams games including WPC.
I know my EBD and Centaur are hinged similar to my Space Station and High Speed where the biggest pain is removing the connectors from the boards. Now there are more connectors and bundle clamps to mess with but the general areas are mostly the same to sweat... power (Bally has a connector) switches, lamps, solenoid drive, speaker.
Also my Bally, Stern, and System 4-7 games have not fit through my basement door as their heads are 30 inches. My Space Station fits as its head is 28 3/4 inches. Same as MM and AFM
YMMV
