Differences between 1997 and 1999

I am currently rebuilding a 1999 F150 4x4, 5.4L and I am looking for a parts truck. Does anyone know of any major changes to these 2 different year models? For example -
Same ABS system components?
Same reservoirs in the engine bay? (coolant, power steering, etc)
Same emissions stuff?
And so on...

Thanks for the help

Off hand the motor in the '99 is a PI head truck and has more power than a non PI ('97 and '98 models). A few other difference in the motors with a few sensor differences and locations. Real early '97's (made in late '96-mid '97) had a different front end mount for the headlights and grill (the header).
I am sure there are other changes, but these are the only ones I know for sure about.

Electrical system is very different. All new electrical box under the hood, addition of PATS and a new instrument cluster all come to mind.

Electrics are different. Doors use different windows/regulators. 97/98 have coils and spark plug wires...99 has COPs.....97/98 has drum brakes on the back, 99 up has 4 wheel disc. And 97/98 doesnt have PATS.
