Just finished the design for the plug and play bracket for the F-U-E-L gauge on Metallica. I know this is not as hot a machine as Iron Maiden, but this really needed to be done to offer a clean solution. Still working on dialing in the colors (the one between full yellow and full green will be changing for sure), but these should be available pretty soon.
There are no "bumpers" on the end to key it like the Iron Maiden because there's a notch on the bottom that goes around a board in the way on the underside of the playfield. If you have it oriented wrong, it won't fit. Also, I didn't know how consistent Stern was with their screw locations because these are individual light boards, so I made them oval to allow for a pretty good range of adjustment.
And how it looks installed:
Here are some other plug and play mods:
