Dorman makes a lot of stuff and they often don't list them correctly for our rigs, so I am going to try to help them fix this. (waiting for a call)
What they do show
http://www.dormanproducts.com/gsearch.aspx?year=1988&make=American%20Motors&model=Eagle&origin=keyword&start=0&num=100
The map light cover (center part) is the same as some Fords.
This can mostly be found on the "HELP!" rack at your local parts store.
Don't take the numbers as 100% correct though. Especially if you have 80-82 early Eagles.
