I've never researched scrub line. But it would not pass a NSRA (National Street Rod Assoc.) inspection. Here in Michigan esp here in SE Michigan, even though it might not be "Legal" I don't see ever getting pulled over for it. The police here won't even come to a accident scene unless there is an injury. They wouldn't even come to the accident scene when my wife was involved in a fender bender caused by a 19 yr kid with no license and no insurance a month ago.
