No problem dropping in the 4900, it will work done
And of the 5-6 pole positions that I have had my hands on, they all came factory equiped with Matsushita monitors. Not saying they didn't come with GO7s, i just always think of matashita when think PP because it's the only cabinet.i have ever seen them in. Most people say they are junk but I believe mine has a better picture than any other monitor in the arcade.
