I have a 1990 dodge w250 and was wondering what years were interchangeable for parts like fuel tanks and body parts like doors. Any input would be greatly appreciated.

 

88-93 I believe will be the most identical match to your truck, there were some minor trim changes and such but the big parts should all be the same, and aside from the grill and interior changes i think the rest of the body parts and such are the same back to the early 80s, another difference you could run into is when the magnum fuel injection started, and the evap system started
