Quoted from gorditas:
The hinges will need to swing out of the way to remove the upper mounting bolt. Are you not powder coating them as well? Are your rails taped on? They are a bear to remove without bending, if that is the case. My MMR had no adhesive, so they came off easily. But on other games that did utilize 3M tape, I bought new rails from Pinball Life. It greatly reduced the stress of removing them, and probably paid for themselves in prep time to remove the adhesive: they can't go on the oven with any tape residue.
Ya I was told the LE run had the double sided tape, not sure on any else
