If it's the door glass, the Gremlin glass is a direct fit. I believe the 2-door Concord/Hornet/Eagle series also used the same glass. The only difference in the doors between the Gremlin/Spirit and the Hornet/Concord/Eagle series is the Gremlin/Spirit window frame is attached about an inch lower at the rear than the Hornet/Concord window frame. Of course, 1/4 glass is a whole different matter....
