It doesn't take much either to mark what leg goes to what place. Just need to emboss the letters "back" or "front" before the sheet metal is formed in the press brake. Or even laser etch it but really you should emboss it.
I like what they did with Dialed In! and their way of leveling though. OR what you can do is hook up an inclinometer to the playfield and have the LCD tell you the pitch, etc on the screen itself.
