Don Shillady---You have expressed concern about the fact that the fiberglass fenders are considerably thicker than the original metal fenders. This is true, however, the fender braces do not actually touch the inside of the fender anywhere except right at the points where the bolts are. The fender braces are designed so that all parts of them except right at the bolts is clear of the inside of the fender by 1/16" to 3/16". This more or less solves the issue of thicker fenders.
