I am going to be replacing the swaybar in my GP soon, as it has holes starting to rust through it. My question is, did all Gbodies come with the same size swaybar? Or did 'sportier' models (MCSS, GN...) come with thicker or solid ones? If so, I'll replace mine with a better one. Also, I thought I read somewhere that GNs came with a rear swaybar too. Did they?
