I just played a MIM Stratocaster tonight that I really liked, S/S/S. I was womdering if The MIM strat pick-gaurd is the same pick-gaurd used on the MIA Strat. Also can I fit Humbkers S/S/H in a S/S/S guitar body of a MIM strat? How is the body of the MIM Strat routed?

The pickguard should be enterchangable between MIM & MIA.
The routing has changed over time. I believe as of 2008 that the routing is a humbucker route for bridge and neck, and single coil route for middle, on both MIM and MIA.

Pickguard is the same.If it is a Standard strat,hum will fit too.Standards are now HSH,older ones are HSS,other series,like classic are SSS....

Thanks. I'm going for it. I'll post pictures ASAP.
