I'm working on this project right now. If the cost isn't outrageous, I'll do it. Otherwise I'll put some or all of it on hold and save for the mechanical stuff I want. (New exhaust,intake,lift etc)
Long story short. I took my obsession with Darth Vader and fused it into a name for my truck and a concept/theme.
I will be having some things fabbed on my brush/bumper guard and then a custom front skid plate, custom bumper (WAY down the road), rear skid plate (after custom rear bumper and lift is done) then custom decals,eye brow and then maybe rear tint/vinyl.
Front Skid Plate
Rear Skid Plate
Custom decals (Thanks 07FX4Chick's for your "sexy edition" decal. It gave me the idea

)
Rear Window
For now (if things go as I want them) the letters on front will be engraved and I'll drill some holes in the field of them and the helmet stencil will be water jetted out. Lights behind and maybe a fake purge through the mouth piece down the road.
Rear skid plate will have the bow tie engraved (holes probably drilled) helmet stencil cut out. Lights to where they are incorporated in with the brake/tail/turn lights. Have the helmet light up brighter on braking and left/right 1/2 of bow tie with turn signals.
The rear tint/vinyl thought is probably just wishful thinking. I don't want anything on the outside of the window and IF it can be duplicated (to real close to) on tint the factory tint of the window would probably distort it.
With the darkness of my tint I can't really see out of my window but, I CAN see out of it. So even if they couldn't do it in a tint application but, could do it in vinyl. I would be blind out the window and again the factory tint distortion factor.
