I'm have a hard time getting my truck done. I took the truck to the body shop about 4 weeks ago, They were painting the rear fender and fixing a couple rock chip. While it was there I asked them to install the fenders. He called and told me I had the wrong running boards? what the heck. I test fitted the new fenders without the running boards,and they were fine.What do I have? could someone give me the dimensions of the stock running boards.
