2003 to 1997 parts swap?
 

does anyone know if the doors from the 03 will go onto the 1997 and any other parts including the interior seats etc, thanks

Nope. Nothing from the factory will swap over.
Roof rack and winch bumper will.

water pump if a 4.0 engine. But the vehicles are not meant for cross breeding - especially the seats.

I'd think the tranny swap might not be as easy as that. I have done the headlights.
