I've heard nothing but good things about the Carvin Bolt kits, although I've never had any personal experiences with them.
I did order a wired Bolt pickguard once though. I got it with an AP-11 in the neck and middle positions, and a single coil size THB60 dual blade pickup in the bridge position. The THB60 pickup was just so-so. I wasn't all that thrilled with it. As to the Ap-11's, I found them to be bright and spikey as wired in the pickguard. The pickguard came std. with dime sized 500k pots that I replaced with CTS 250k and re-wired the pickguard like a Strat, removing the coil split switch and adding a second tone pot. This turned the AP-11's into totally different animals. While they never did get a true vintage single coil vibe (they're ceramic magnet pickups), they were very useful single coils none-the-less. They surprised me to the point where I really couldn't find any fault in them. They deliver nice musical tones. For the record, I tested this pickguard in an alder bodied Strat clone with a maple/rosewood neck with a Fender type single truss rod.
I would avoid the C22T bridge humbucker. I have one, and it's one of the brightest, spikey-est humbuckers I think I've ever tried. The only way that I was able to turn it into anything approaching a usable pickup was by changing the Alnico 5 magnet to an Alnico 2. Even after that, it's only a fair pickup. The M22 and H22 humbuckers are both much smoother, and more toneful pickups. BTW, I wouldn't recommend trying a magnet swap in a Carvin C22 pickup. Instead of the vintage style construction using screws to secure the coils to the base, Carvin hot glues the coils to the base. They're a real PITA for changing magnets.
