I have a 67 2dr with the factory 4 piston caliper disc brakes. My rally rims don't clear so I have some crappy universal spacers on there for now. I can't find any specifically for an impala so I ordered some for a camaro the same year that have their own studs. Is this a bad idea? What do you guys recommend I do?because I want to keep the rally's on it because I like the look.
