Step 2 is to install the plate and bolt it in. Note the tape on the center picture it is so the bolts do not fallout when you put the nut on.
Installing Rowe Kit #27040201 High Security Bill Acceptor Inlet
I am actually installing a High Security bill acceptor on a BC-1400 not a BC-200 this time.
Their are 6 bolts that need to be removed and that is all that I did today. It was a lot harder than I would have thought.
