Great story! When dealer parts were mentioned, it reminded me of when I was restoring my '69 300 in the mid 80's. I needed a new front valance for under the bumper, since mine was bent and rusted out. I went to Roseville C.P. to see if I could still get one. The parts guy checked, and sure enough there was only ONE left in the system! After it came in a week or so later, he told me that particular part number had now gone NS1. I got extremely lucky when I ordered it at that time.
In 1987 I had a Lil Red as a daily driver. I needed a couple parts so I went to the closest Dodge dealer in McHenry, Illinois and they still had a complete engine wiring harness, plastic tubes for the air cleaner hoses, dash harness, and various little parts that were unique to the Lil Red. I should have bought all that was left...
