They should. I've switched from MIM to MIM before. Not sure about special order ones, though.
The description says "with set screws for really secure mounting on all split shaft pots." So check your Stratocaster's pots and make sure they're split shaft. I don't have a Stratocaster but I have switched out the knobs for my Jackson which has a split shaft pot and I have to tighten the new knobs frequently. Buyer beware I suppose, although I may be an exception since plenty of people across the world change out knobs everyday without trouble.
Yeah, they'll fit, but the extra height will mess with your tremolo arm.
Actually, I go by Dave, but there are already too many Daves on this forum.
