Neo Geo control panel for Astro City?

Hi all, I just lucked into an Astro City last night. Are there any Neo Geo specific control panels for this machine, or is my best bet the 2p Capcom layout, using Capcom's "button 4" as the Neo Geo A button, and then buttons 1, 2, 3 as Neo Geo B C and D?

Sorry if I posted this in the wrong place, wasn't sure if I should put it somewhere else, but "Tech support" didn't seem right either.

there are panels that have a Neo-Geo style layout, here is one...

I don't expect you'll see a lot of them around though, most are 6 buttons per player.

Sanwa made a 7 button per player one that is good for both Neo Geo and Capcom stuff.
