I feel your pain. I've been waiting two weeks to install a JB in my new HSS Strat, because I had to order a replacement pickguard. Finally got it wired up late last night, and I can't wait to fire up the amp and give it a go.
Taking the guitar apart was no fun, either. I'm used to loosening the strings on my Les Paul and being able to replace the pickup without significant surgery. From what I can tell, there's no way to do this on a Strat without replacing the strings, but I'm certainly willing to listen to others who have figured it out.
