Yes I know that some of the NHRA cars and IHRA cars also have slightly narrowed rear housings. Who really cares as long as it looks correct. I was just saying that the amount they moved the leaf spring for side wall clearence was usually less than 3/4 of an inch on each side. This is in comparison with all of the body work required to fit a 9 inch stocker tire on some body styles. In time I hope IHRA changes the wording in thier rule book. A 9 inch radial is quicker than the 10.5's anyway.
