went to change over the buttons in my new jamma cab with the buttons i got from ultimarc (for when i was going to build a cab) and turns out they wouldnt fit. the existing buttons are smaller in diameter than the new buttons i've got.
bit of a predicament now coz i dont want to have to drill out bigger holes in the cp coz it's in really good condition (complete with glass/perspex overlay).
i guess there is no alternative?
