Currently replacing my front sway bar bushing in my 2010 dodge avenger and it seems to be really hard to access the back and front bolts. Did anyone replace these bushings themselves and what did you have to remove?

I have a 2008 Avenger R/T and I want to get a bigger sway bar in the rear. The stock one is 19mm, does anyone know which Avenger Trim/Year has the biggest bar?

I have a 2009 SXT and I would like to install 2013 R/T sway bars. Both front and rear. Is this just "bolt on"? Are attacments to body in same places and do end links fit? I would really appreciate if someone had info about this.
