It's the body panel that goes between the rear window and the trunk. Does anyone make reproduction panels for 4-door Cutlasses? I've seen panels for 2-door machines, but they're a different shape. I think 4-doors use the same filler panel as convertibles.

 

Welcome to the site! I think you'll have to find a good used one from a parts car. I believe 66400 (Henry) has 1966-67 parts cars. If you don't get a reply to this thread try sending him a PM. John

 

Yes -- I see that this is a very old thread.

I met a 66 4 door F85 owner at a car show who needs the same 4 door rear deck filler (tulip) panel referenced in this thread. Is Henry, referenced in the thread above, still around? I see this post:
