I was sent a PM about the washer container. Yes, originals opened front to back. This container was on the car in 1990 when I bought it, the container was already quite yellowed. It was probably a Chrysler parts counter purchase in the late 70's, early '80's. Someone at Chrysler determined that it made more sense to have them open back to front and started making the service counter parts supply that way, so they couldn't "blow open in the wind". Why most reproduction suppliers in the 21 century started doing the same, duplicating the parts counter piece vs OE.
