OK, then if worst case you need to make your own back is easy to print. Not sure about the gold though?
Maybe shoot Jeff at Classic-Arcades an email to see if their planning on making them.
For me - mylar removal is an absolute last resort if there is serious wear or peeling etc...I've had success on two playfields with mylar (PoliceForce and Op Thunder) which had very dull mylar and I brought out a great shine from cleaning & polishing. (Treasure-cove kit).
With clear over decals - I've read that its been done without issues. On my T2 (Pete's now) and Police Force aprons - both times clear has gone down over decal and not been any issues what so ever.
