Hey Chuck, sounds like a cool project. How much are Stewmac charging for a neck pocket template including shipping ?
I'd recommend making your own template as you will learn a new skill, save money and probably get a better fit depending which PBG neck you purchase.
Note the tele and strat neck heels are slightly different, the strat is more rounded and tele is squarer.

I used the standard Titebond red label glue, should be available from good hardwares.
