What model truck do you have, Styleside or the flareside? The front fenders are available from several aftermarket suppliers.
The Flareside bed is not available, but the Styleside may be. You may want to consider using a later model bed which are easier to find at the auto recyclers. Check out Bichun Truck parts in Warwick, RI. I know the sell new fenders, grilles, headlight buckets etc. Telephone # 401-737-2524 ask for Dave or Ron. Hope this helps.
