so a little bit of an update:
i went ahead and drilled a new hole in the headlight sensor bracket to move the ball joint out away from the frame mount.
i also played with the extending the rod ends to push the top of the tire out. with the UCAs on the truck, its really hard to measure accurately to the center of the eye rod like they say, so i kept it conservative to not go beyond the limit the prescribe. i got a to where i had clearance while parked but would still rub once moving.
i took it to get realigned and asked them to bias my camber to the positive side of the spec, which they did, but only just barely. ill likely take it back and ask for a little more positive camber(but still in spec) and i think ill get the clearance i need.
what is confusing me is i just found a guy on one of the facebook groups with the billet ucas and stock wheels but 35x12.5 tires and he claims he only just barely rubs at full lock. but my tires are an inch skinnier, so you'd think id have plenty of clearance.
