B series Paystation from PDQ coin box?

[cap732000]

I bought a PDQ B series paystation a few months back off car wash consignment and as we were getting ready to install I realized that it doesnt have a coin dispenser. I can get refurbished ones online but im not sure the coin capacity as there are 4 different sizes related to that part with the AZKOYEN. Im almost positive its the smallest one but not sure. Any help would be appreciated.
