Help with a dixie-narco

I have a dixie narco coke machine, it appears to be from the early 1980's or so. It has 5 buttons and 6 columns for cans or bottles.

The colums are labled 1-6 on the inside of the machine, columns 5 and 6 do not work. In cloumn 6 the motor turns but the tray that dispenses the cans does not spin. I can turn it with some difficulty if i reach in with my hand and turn it but it will not turn when i press the button, the motor turns but the tray remains still. Is this a difficult problem to fix?

In column 5 it seems as if the small switches on the inside of the machine are not working properly, one is somewhat bent and when i press it nothing happens. No motor turning, no sound no nothing? Can these switches be obtained simply by going to a radio shck or will I be on a used part search to try to obtain these needed switches.

As a novice to the world of soda machines, any help anyone can give me regarding this machine is greatly appreciated.

Thank you
