Since moldings were body color that year and your car had a regular production color (EL Wild Strawberry Metallic), I would imagine that the "I" Mldg code on the door tag means Wild Strawberry, or something similar. I have seen one other door with the same Mldg code, and that was also a '92 painted EL (
Pennsylvania State Police NF109533).
A DSO number of 0517 means it was special order # 0517 for that model year.
