Heavy gauge steel construction.  Most front fenders are available in three different widths (measured inside fender).  Fenders are inspected personally by a master fender builder to assure straightness, consistency and a flawless finish with an absolute minimum of finishing bodywork.  Fenders come un-drilled (unless noted) so you can position them to look and work best for your application.  The predrilled fenders may need spacers.  Handmade in the USA.
