This. I even put a dab of grease on the backside of the eccentric washers so that the camber bolts rotate easily when making adjustments to the alignment. I use stock (old) camber bolts too, I've only ever retired one set of camber bolts and that was because of the heim joints on the Hotchkis UCA's on my Challenger going bad and wearing the bolts.
The torque spec on the camber bolts is 70 ft/lbs.
If the UCA's and bushings are new, I would readjust the alignment and make sure to torque the camber bolts to 70 ft/lbs with a good set of lock washers in there. While you're doing that you can check to see if the UCA mounting points look decent. If they're broken or rusted out it should be pretty obvious though.
