NOTE: What I mean by "mark" is the same as used in the car business, so the marks I am interested in are:

- Gottlieb wedgehead

- '60s Bally 1-player

- '70s Bally 4-player

- '70s Gottlieb 2- & 4-player, before the big change in 1977

- '60s Williams 1-player

- '70s Williams 4-player (although since this shares the same backbox as the '70s Bally 4-player, perhaps it is the same "mark")

I am swapping out all of the backdoor locks to keyless thumb locks, and I want to use the proper latch style, in case it's just not the simple default style that comes with locks, such as this:

I am using the OEM for the SS titles, so this is only an issue for my EMs.
