There isn't another camber bolt kit you can buy, you have to use what's there.

Make sure the front is high enough, if it's not, you'll never get it within spec. Between 0.75" and 1.0" between the bumpstop and arm.

Are you doing this yourself or having a dealer align it ? If you're doing it yourself, you'll never get it, since the upper arm controls 2 things, camber and caster depending on how you adjust the front and rear bolts.
