I have a nice 1996 Ram 1500 extended cab 4x4 Laramie SLT SPORT with the 360 in it and I love it. Owned it since it was new. I am in search for a rust free drivers side door due to the sad MN winter rust. What all doors would fit on this truck? Remember it is a 96 so it does not have the rear half doors.

 

Any Ram single or Club Cab doors will fit. Just not the Quad Cab doors.

Basically, you're looking for a door with a curved edge at the bottom rear of the door.
