You can't put the bridge position ones in, since they wouldn't fit; they have 3 screws in different positions from the 2 used in a Strat and unless you have a swimming pool route, I doubt the base of the pickup will fit in either.

May I recommend the SD Twangbanger? I think that's designed for to make a Strat sound like a Tele.
