Not sure if this will be of any help to anyone but I noticed as I was reinstalling my door weatherstripping and door handle parts after the paint job that all the weatherstripping that has little plastic plugs that go into the door and the door handles both are color coded for each door. Meaning the little plastic tab on your interior door handle that hooks to the rod that opens the door is white for the left hand side (driver's) and yellow for the right hand side (passenger side). Ditto for the weatherstripping: The plastic plugs that fix the weatherstripping to the door are white for left hand side, yellow for right side.
