Get a 'Progress' RSB spec'd for the 95-99 Maxima. Fit's like a glove on P11's. I know I installed my almost 2 months ago! And a short while after that, Loek installed one on his P11 too! BTW, I spoke with the guy I bought mine from, and he'd be up with me setting up a group buy for these. And he's offer a great price too! However, I misplaced the the sheet I wrote it all down on. Either I find it or I will just call him again. The best part, people can pay him direct. I don't need o be the middle man for the $$. I'll keep you posted!
a progress rear sway barwill from a 95-03 maxima will fit on the p11 g20 without a problem. If you are looking for one check the group deal section of maxima.org. That is where I bought one for my maxima and my p11 g20.
