Same door frame. With the top monitor, you need to be careful. The monitors Bally uses for the bottom has a thicker metal frame than the one used in the top door. I ran across this issue when I converted a V20 to a V20/20. I was going to use a monitor from another V20 to put on the top box. I built the bracket out of thin aluminum sheets, and the monitor fit fine in the frame, but when I tried to close the top box, the monitor's thickness would not allow the door to close. The monitor's thicker frame interferes at the hinges, lucky for me I didn't just slam the door, otherwise I would have killed the monitor. I was able to source one of the thinner frame 20" monitors and used my built brackets (which had to be further modified as the mounting holes do not match) and the top door closed correctly as it should. So if you do source a monitor, make sure it has the thinner frame. When I get home tonight I will measure the frame thickness for both monitors so you have that information when you source your monitor out.
