     BACKGROUND 
     Field 
     This invention relates to synthetic boards used in vehicles, specifically boards used in the cargo beds of pickup trucks. 
     Prior Art 
     New pickup trucks now feature a cargo bed that gives a one piece streamlined affect. Early model pickup trucks have used wooden boards for the floors of the cargo beds. People restoring early model pickups have gone to great lengths to capture the original classic wooden floor boards for their restoration projects. 
     When restoration of a vintage truck is complete, new wooden boards are placed in the bed of the truck with care to maintain a show room result. Wooden floor boards, while giving a classic appearance of the original truck bed, are prone to fading, moisture absorption, decay, and warp. Additionally, wooden boards are less resistant to abrasion than the new steel beds that replaced them. The ideal board would give the appearance of wood with abrasion and weather resistance. 
     U.S. Pat. No. 6,431,629 to Emery (2002) utilizes layers of thermoplastic and colorant to provide impact resistance, appearance, and slip resistance but is not suited to replace a vintage truck bed system. To gain acceptance in the truck conversion market, boards must have an antique appearance that is only provided by individual boards. A 3D effect may be printed on a one piece floor system to simulate individual boards, however this is not covered nor taught within this prior art. 
     U.S. Pat. No. 8,136,860 to Wise (2012) and U.S. Pat. No. 7,618,075 to Boddie (2009) offer novel means of protecting a modern truck bed. These inventions use finish and impact absorbing layers but are not suited to the conversion market for the reasons mentioned above. 
     U.S. Pat. No. 5,083,830 to Mucher (1992) teaches of a one-piece method of inserting a decorative and protective layer to a truck bed. Although this apparatus could be manufactured with printed images, advertising, and even wood grain patterns, no provisions have been made to adapt this concept to fastening to the many variances of support features found in vintage truck beds. 
     SUMMARY OF THE INVENTION 
     According to one embodiment, the improved truck bed floor system ( 1 ) is furnished in a kit to be assembled and installed by the person restoring a vintage truck bed ( 2 ). Each board ( 3 ) consists of a structural base ( 4 ), an image layer ( 5 ), and an abrasion resistant layer ( 6 ). The image layer can be printed vinyl, produced using emersion graphics, or printed directly using the board as a substrate as opposed to traditional paper. This image layer ( 5 ) may contain a wood grain, advertising signage, or any custom image. The abrasion resistant layer ( 6 ) is preferably clear vinyl or PVC of the type commonly used as protection in floor graphics for retail stores but may also be a liquid applied to the image layer. Formed retaining clips ( 7 ) are installed against the protrusions ( 8 ) of the board to capture the protecting layer and clamp the board in place. Fasteners ( 9 ) are inserted through holes in the clips and into the bed frame of the truck ( 10 ). 
     One embodiment of the floor board consists of an aluminum extrusion that has a two outer legs ( 12 ) and may also contain a center rib ( 13 ) for added strength for wide boards. The outer legs ( 12 ) may also contain a foot member to keep the board in place during the first application of the retaining clip ( 7 ). A pocket ( 14 ) in the side protrusion ( 8 ) receives one of the legs of the retaining clip ( 7 ). Several boards ( 3 ) may be used with outer boards ( 16 ) trimmed to fit to reach the left and right side panel of the bed ( 2 ). Additionally, the outer board ( 16 ) can be manufactured narrower than the main boards ( 3 ) and may contain one or both outer legs ( 12 ) and may also contain a center rib ( 13 ). 
     Prior art in the truck industry relies on wooden boards ( 17 ) with a machined or formed side protrusion or tongue to accept the retaining clip ( 7 ).
