I've been running a thick (.06?) washer under the front screw on the old skool arms just using thinner washers to adjust ride height on both front and rear screws to make up for tire thickness.
Also on the paper shims for the camber adjustment, I use a tiny strip of tape at the leading edge, just after the front washer (.06) to hold the paper strip in place. It makes adjusting the ride height shims that much easier. Once in a while, when cleaning up the car (minor rebuild) I will change out the header card strip.
