If you go for a full resto, just getting the parts will cost as much as you paid for the guitar. Then, you have to factor in the cost of filling the hacked out wood, stripping and refinishing. If it were mine, I would change the things that bugged me the most and leave the rest alone. I know that bridge and pickup would have to go in favor of something more authentic, but I wouldn't hold out for vintage parts. I'd certainly clean up that electrician's dream, and get that humbucker in there straight.
