How are you with vector graphics programs and so on? Ideally you want to have a plan ready to check out its all going to work. I've got a project in mind to make a Fender 66 shaped body, so I got the best photos I could for the shape, and then went hunting on a forum for someone who owned one to get a couple of key dimensions, and I'm now confident I have something very close to the Fender shape and size. And discovered it won't come out of a Strat body, I need a new piece of wood.
So in your place I'd research the best photos and things I could, and see about producing a full scale plan. You can probably find an Explorer drawing on line, and in any case there are surely folk here who would help. But it depends on how easily you can find good square on photos of the destroyer, and better yet an owner who'll give you numbers. Maybe an Ibanez forum? Presumably such things exist.
