Thats cool, I have seen this done myself.
I bought a Vendo 110 one time, It was originally a 6 case vertical with a large coin door put on it, It had a large door change giving mech, and a VMC bezel on it. They stuck a bottle stack in it with the proper shelves. What was odd was that the coin door lock brackets were hand made.
They could've had a damaged or vandalized 81D and a good 81A body and made it work?
