1975-79 Corvette Bumper Covers & Retainers Exploded Diagram - ZBU-389, SRB-077

This scanned catalog/reference page shows exploded parts diagrams for 1975-1979 Chevrolet Corvette bumper covers and their retainers. The top-left panel pictures a single Bumper Cover Retainer with part number ZBU-389, and the top-right panel shows a Bumper Cover Retainer Kit consisting of multiple retainer clips and nuts arranged for installation. The main center illustration, labeled "75-79 Bumper Covers & Retainers," contains two exploded views: the front bumper cover with callouts identifying the Upper Retainer, Outer Retainer, and Lower Retainer, and the rear bumper cover (with its four round taillamp openings and license plate recess) showing the Upper Retainer and Outer Retainer positions with fasteners. The bottom panel is a photograph of a TruFlex Rear Bumper Cover, part number SRB-077, showing the molded urethane rear cover with four taillight holes, embossed lettering across the face, and the recessed license plate pocket. A reader can learn which retainer pieces attach the front and rear flexible bumper covers on 1975-1979 Corvettes, where each retainer mounts relative to the cover, and the aftermarket part numbers for a replacement retainer (ZBU-389) and rear bumper cover (SRB-077).
