Spirit door will fit the Gremlin but the window frame slopes down towards the back on the spirit. So they dont seal up at all on Gremlins. The frame and glass can be changed from the Gremlin door if neccesary but its not worth the trouble.... jeremy Tried to swap doors from a spirit learned the hard way..... << karla,the fenders from a 70-72 Hornet will fit a 70-76 Gremlin,also the grills are interchangable,the hoods from a 70-72 Hornet will interchange with a 70-76 Gremlin also the doors from a 70-77 Hornet,78-83 2 door concord,79-83 Spirit and 80-? 2 door eagle will interchange with the 70-78 Gremlin basically the above cars share the same platform.
