When I added service rails to IM, the holes for the t-nuts were already pre-drilled at the factory under the apron, so it was just a matter of putting the t-nuts in place. The bottom/back holes go wherever there is room, the above pic is a good reference. In fact you don't even have to remove the pegs to install the service rails, there is enough room.
Quoted from Lethal_Inc:So the new machines don't even have the black playfield legs to rest playfield on cabinet anymore? Or did you just remove them to install these service brackets? Man what a shame, first they take away the nice back box lock and now no service brackets or stands? How am I supposed to justify spending the amount of money I am right now for a NIB led pro and they give you bare minimum stripped down games. Huh, even the knocker is gone. Maybe I'll keep my money instead this is f$&#in bullshit.
All Pros ship with the black pegs. What's with the lock box lock missing? I'm also not aware of a pinball machine made in the past 15 years with a real knocker...
