The original was one of those nasty ones that deteriorate while leeching out some corrosive gunk which trashed some of the pots and pickup selector switch.
I was able to work up a trace and transfer it on to a template, the only hard part, which was why it took a few tries, was the neck pickup opening, which I finally was able to sort out.
I had a the router slip on the end and mess up the back edge but I decided to let it go and just put it back together so I could play the damned thing.
Not only do I need to replace the nut but, after wiring and rewiring and rewiring, I discovered the bridge pickup needs a rewind. Once I get that done (it'll be awhile, I'm unemployed!) I'll redo the guard one more time.
I'll still need to finish replacing the nut and I'll have to fill in and redrill many of the the pickguard mounting holes.
