Yep, they will fit without a problem. I had them on a 2011 crew cab sport. The chrome side steps will also fit your truck. If you would want both, I would make you a great deal.
Hi Bill, I think it's 9", but I will check when I get home I can't remember where I bought it. I thought autoanything, or Amazon, but I looked at my past orders and it wasn't through them.
