Arcadeshop.com has repro metal plates that stick on and cover the rivet holes in the door. I have on on my Pac Man and it looks great.

They have 2 differnt versions of the silver.
My coin slots swere nasty and rusty untill I used a die grinder with a buffing wheel and rouge (sp?) on them and they look brand new now!!Also buffed the coin return buttons, sandblasted the door and put a fresh coat of paint on. Looks really nice.
I have a door, its not midway and only one slot that I have restored that you could have for cheap if you didnt want to screw that one up. I also have a new Happ coin mech around here too. The door doesnt have the mounting bracket for the coin mech but I believe the Midway will work fine.
