In Dallas, call Truett-Worral and ask them. They may or may not do something as small as your truck but if anyone knows who could do it, they will. Before I did that, I would look closely at your front axle beam. Years ago a friend of mine had camber adjusted on his truck and the shop discovered it was simply a matter of the axle beam having been bent. How? No clue but for some reason it was not straight and level and this caused the camber on one side to be off a wee bit. In his case it turned out to be less expensive to fix as they just had to straighten the axle. From what he said the shop told him that wasn't so uncommon. Good luck.
