http://www.modsats.com/?s=ford+svt lists 3 pages of Ford F150 SVT Raptors with different version numbers, but they don't look like versions of the same model. Some have more added aftermarket headlight bars than others. E.g.
v 2.3 has 5 headlights on top and 4 in front of the bumper,
1.5.1 4 merely in front of the grille
1.1.2 has 6 on top, and 4 in front of the bumper.
