1966 saw things at Lincoln-Mercury starting to get a little funny. The Plastigage Corporation was enlisted to produce four fiberglass Comet bodies for each of their match race drivers. From the outside, they had the appearance of stock bodied Comets, except Jack Chrisman's GT-1. Jack hacked the roof straight of his car and turned it into a wild roadster. This roofless wonder was a very strong performer, running over 180 mph in the quarter, until parachute failure destroyed the plastic projectile. After running out of strip and stopping power, the GT-1 crashed, burning to the ground.
