Body Parts Intechangeability: Hinges, Door Handles
From Eaglepedia
BODY PARTS INTERCHANGABILITY
Station Wagon Hatch Hinges.
They are interchangeable between all model years. They are NOT interchangeable from side to side. Each side had a distinct curve to match the bodylines. Hinges from a Concord wagon will fit Eagles. They were basically the same body.
Exterior Door Handles
These are interchangeable front-to-rear. They are NOT interchangeable from side-to-side. Handles from a Concord or Spirit will fit Eagles.
There may be a difference between handles for doors w/ power door locks, and those without. I will check on this at some point.
