Also, from the looks of it, you have headers. It is a common problem for the middle spark plug wire on the back side to rub against the header and cause it to burn and short out. When you install the new ones, make sure that all the wires area away from hot surfaces.
Thanks!! Yeah, have a set of TOGs. I do have the intense boot shields on the plug wire ends, but that's below the headers. I was gonna get some wire looms anyways, but this will make sure that it don't do this again.
