Note that the PinOne Mini board that comes with the plug-and-play kit does not come with the wires to connect buttons (all my buttons come with the connections that plug into this board). If you need wires to connect to other buttons, I sell them here
Another great feature of this plunger is that it is the only one that can be mostly assembled outside of the pinball machine, which makes it much easier to install than other plungers available. Installation instructions and video instructions of latest version
I recommend purchasing this shooter assembly from pinball life: Pinball Life: Williams/Bally Ball Shooter Assembly. If you choose the option to include the plunger, this is the exact assembly that you will get.
This plunger will mount to the ALP plunger, but it does not have the connections to the ALP. It is designed to allow you to connect to KL25Z or a PinOne board so that you can play VPX or FX tables with plunger support but can still keep the ALP plunger.
The approximate dimensions of the williams style plunger are:
*Plunger base (the part that shows on the exterior of the cab where the plunger knob is pulled)
Plunger base to end of the plunger shaft: 6.5"
Plunger Mount screw holes to end of plunger shaft: 6.25" (this is the distance the plunger will reach from inside the machine)
Plunger base: 2.5" wide, 2.875" long
Plunger Mount screw holes: 1.8125" wide, 1.5" long (this is the hole you will need to drill out to fit your plunger)
If you want to add the plunger directly to the PinOne Main Board, you can follow along with the video to the right! (Main board sold separately) Of course, you can use the Mini Board, which comes in the kit in this listing!
This video of the Mini Machine assembly contains a PinOne Mini Board with the plunger! It may help you with assembly!
