in 1980, amc entered into an agreement with the griffith company for a convertible body style eagle, and a prototype version was developed. the cars were marketed during the 1981 and 1982 model years as the sundancer conversion. the eagle's monocoque (unibody) body was reinforced and a steel targa roll bar was welded to the door pillars for passenger compartment protection. the front portion of the roof was a removable lightweight fiberglass hatch, while the rear section of polyvinyl material and the back window folded down and had a boot cover when in the down position.
