I've been lookin' for some wheels for my Regal. I used to have a set and always called 'em "knuckles". Thats what everybody else called them also. Thats what I'm lookin' for now. They aren't easy to find let me tell you. Anybody have any ideas. Also, if anyone knows if "Knuckle" is the factory designation. If not, It might make things a little easier if I knew the proper name. Any help with this would be greatly appreciated. Thanks in advance.
