I am looking for a Mopar part number 4310 096 Arm, Door Check. It is the part installed inside the door and it keeps the door from closing after it has been fully opened. It has the curved arm that extends out the door and is bolted to the body with one large sheet metal screw. It is for the front drivers door, but it should fit either side of the cars.

The picture is for the part for the 1983, but that won't work on the 1984-1987 models. Neither will the door check arm for the 1984 rear doors fit the front doors. The 4310 096 part number fits all three years 1984 through 1987.

I couldn't get the picture off of my phone for the actual 1984 part. But that part isn't angular at all, but has a gentle curve more like a banana shape.
