Yes it has , so you are saying that purpose built tube chassis can be compared to a street car?
NASCAR has not ran a production cars since sometime I believe in the 70's, that is when they started switching over over to purpose built tube chassis, that is no longer a "stock car " at that point. Sure, the bodies were production, but those were panels on a purpose built chassis, and even those body panels were massage and change to fit templates back then.
Are you really trying to tell me that the twisted sisters cars of the pre COT days were comparable to the street cars?
