One of the great benefits of the cabinet I bought is that it came with a nearly complete coin door. Only the coin validation mechs were missing. The coin door alone is worth more than the $61.00 I paid for the entire cabinet!
Here's the coin door as I received it. Note that the right price insert has faded almost completely. I scanned the good insert and printed a copy on my laser printer.
Here is the back of the coin door; note the missing coin mechs.
Here is the coin door with the coin mechs installed. I mounted two additional coin switches where they would be triggered by the coin return buttons; I use those for free play. These added switches are circled in red in the above picture. They go to a switch block left over from an ancient AT-clone desktop case, so I can turn off the free play buttons if I want by opening the coin door and flipping a switch. The two extra switches were $3.00 each from Happs, and I spent $4 on the extra switches in the switch block. The wiring harness for the coin door was made from wiring and connectors scavenged from the back of the old control panel. The block (seen below) also has buttons to add credits. This block is mounted inside the coin door.
And finally, the completed and reinstalled coin door:
