Did some checking quick and everything I've seen says that GD is the sedan, and GG is the wagon. I've got a bugeye wagon (apparently a GG then) and am interested in a rack as well. Does yours hook onto the body or the factory roof rails? Thanks.
@idget I just missed that sale on Craigslist for the roof rack last night. I was gonna go after some dude already went to check it out but he ended up buying it for $100. It was in poor condition though.. Let the search continue!
