Mounting hardware for that mini CP? As noted, 180 degree what's on the CP now and it should lock down, assuming the fasteners weren't moved. I'm referring to the pictures posted above.
Twobits was good quality, but had the Namco licensed text, I'm pretty sure High Score Saves has the Midway licensed text. Most collectors prefer the Midway as that's how they originally came. Mine has the Two bits repro, but I have the other one to change it out when the time comes. That may be sooner rather than later as some kid decided to pull up a corner of the polycarbonate laminate, which you can see is the same corner the Namco text is in.
