Since I'm putting wheel spacers on 4175 I have ordered some cleartastic that goes behind the wheels to avoid rock chips. I wanted to get sheets of it to cut and put in other places for road trips. Although I was told that I couldn't just get it in sheets the guy said that he was hoping to get a Bullitt to do a test fit. As much as I would love to drive to Long Island to get it done I just can't justify driving that far. If anyone is in that area and would be interested let me know. If you know where to get sheets of the stuff that would be great as well.
