I'm getting ready to build a light bar for my 2 dr. After looking at the trucklet, a lot of depends on the truck and the owner. Examples:
If you have a 2 pc hardtop, you could mount lights on the bars that are on that (at least mine already has bars). But only if you never take the tops. Or you could mount a bar between the two tops, but only if you aren't going to run a soft top, unless you make the bar high enough for the soft top to go under it and mount it on the sides. Only other option is to mount up all the way up front above the windshield.
Mine is going to be between the 2 hardtops and be about 3-4 inches off the body. It will curve down on the ends and mount on the sides of the B pillars...
Hope this helps
