Is this what you are talking about?

Not exactly but very similar. Ours looks drilled for a seal. I would think this would work. I have some regulators here in the shop that are similar, just slightly larger.

As for pics, the valve is behind 2 battery cables and a mess of wires and air lines. One line goes to an electric/air control of some sort. I can't follow the second air line but it appears to go down.

Ill check in daylight as to how many 6 packs.

Thanks, Mark
