How many shims for Ride Tech A-arms for 69 F-body?

[jlwdvm]

I am trying to get my camber set on my 69 firebird with stock sub frame and Ride Tech stage 2 front suspension set up. I have about 5/8" of shims on each side at the moment and I am at 1 degree negative. Does this sound right? I am using a Harbor Freight digital angle finder and checking on the brake rotor and also on the center cap area of my wheel. Any thoughts?
