Need Advice Camber Bolts 2010 Charger

[10chargers]

2010 Dodge Charger  Had my Charger aligned and have negative camber beyond Manufacture specks on front .     So for front purchased Moog Camber Bolts.   There is only a bolt and nut in this kit.  Install instructions are bit confusing.  I would like some friendly advice before I start this project.   The new camber bolt has groves along each side that appear to slide in lower control arm on "Bat Wings"  inside the control arm assembly.  I  assume these "Bat Wings"  slide into the groves of the bolt.  Apparently, there are more then one set of  "Bat Wings" in this control arm to make camber more positive or negative and the bolt will need to be rotated 180 for it to fit according to negative or positive camber (confusing???).    Since, I have too much negative camber I assume I need to install the bolts on the "Bat Wings  that would make  more positive camber.    Is all this logic correct ??   Any hints or tips? Will i need to support the control arm with a jack when I initially remove the old camber bolt.    Any pitfalls to look out for?  Seems fairly easy job just do not want to make  any rookie mistakes. Any help or advice from anyone that done this before would be appreciated.

Thanks Much!
