Specialty Products camber/caster bolt kit

Does anyone have any experience using Specialty Products camber/caster bolt kit to achieve more positive caster? I understand the go-to solution is Moog offset upper bushings but the set I just received were seriously out of spec, .015" oversize on the outside diameter and .020" too long on the inner sleeve length, compared to the old ones that I saved. (never throw anything away!). And the washers that are supposed to fit inside the inner sleeve - not even close. On all 4 bushings. Sending them back to RockAuto and see if the replacements they send will be any good but I don't have a good feeling about it. Was thinking Mevotech bushings and the bolt kit but want to see if anyone has tried the SpecialtyProducts kit. Thanks in advance for any replies.
