7.3
#4
The 6.0L was kind of a 2003.5 model year release.
As long as they have the big mirrors:
6.0L have the lighted mirrors.
7.3L are solid plastic w/o lights.
(unless upgraded by an owner)
6.0L have a billet looking door badge.
7.3L have a plastic embossed letters door badge.
One of those two will give most of the trucks away from a distance or when shopping online before digging deeper.
