I don't think I would loose any sleep over the bolt diameter. there's engineering,testing and lawsuit prevention that goes into any reputable suspension components. you take in a couple camber bolts to a alignment shop they will probably act as they have seen them before, but they look under your rig and see you have "home brew" alignment that involved a grinder,welder and maybe a Pulaski on a strut they might have some conviction about working on your rig.
