Cavalier machine help

I recently bought a machine, I think its something close to a Cavalier CS64  maybe a D or G, or maybe something else.  I was wondering if it would accept and vend current 20oz bottles? If it won't normally do that, can it be made to? And also will it work with the plans for the free play button shown here? Thanks.

Dan,

I'm not sure about the 20oz bottles... I would think the diameter is a little too large to fit through but you could try...
As far as the free vend switch is concerned, this works on most 110v coin mechs like Coinco & NRI. Just remember to unplug the machine prior to making the connections!
