I have attached pictures to explain what I have on my 69. For each side, there is a small splash shield stapled to a bracket. The bracket is then mounted with the fender extension brace. The bolts first go through the bracket, then through the extension brace. I measured the extra piece that I have and it is roughly 2.5" wide by 3.5" long. There is also one corner cut off from each piece. Both of these shields look to fill the gap between the frame and inner fender. Basically an extension of the "3rd and 4th" splash shields where they do not reach far enough back. Does anyone have this "5th" shield? What size is it? I wonder if you are supposed to cut it in half to use for both sides?
