I dunno what "site" you've been going to then, because hidplanet's forums are about as detailed as they get. If you don't get it from reading up on that forum, you probably shouldn't be attempting the project. There's even a guy on there who started his own retrofitting business and will do any car, although I'm sure his labor comes at a cost. You can buy mine for 2 grand :lol: cuz there's no way in hell I'm parting with them for cheap.
