Any idea where to get a reasonably priced replacement OEM (or OEM-like) coil rail bolt (just one)? I have 3 of the 4, and the 4th bolt is a stainless bolt that's shorter and a smaller head. It works, but drives me nuts every time I look at it or have to remove the rail and have to use 2 different sockets to do it. Not paying $30/bolt like I'm seeing on ebay.
