I think I don't have the original pick-up ... anybody knows what kind of pickups were originally on these models ?

thanks...

This isn't really going to be of much help, but those were just American Standard Strats with a metal "40th Anniversary" pin on the front of the headstock and special engraving on the neck plate. Therefore they just had "American Standard" pickups. Unfortunately the 1986-1996 American Standard pickups are not the same as as the current American Standard pickups; American Standard pickups were changed at least 3 times since your guitar was built:

circa 1996 - the "Delta Tone" circuit is added; the neck and middle pickups are the same as they had been since 1986 but the bridge pickup was changed to a slightly more powerful pickup.

July 2000 - the "American Series" replaces the "American Standard"; new pickups now have staggered polepieces.

January 2008 - the new "American Standard" replaces the "American Series"; the pickups are again modified.
