I understand Denny. I grew up around the local Dodge dealership and spent a few years in the parts dept.

Part number changes and price changes were a way of life. People don't seem to understand that the manufacturer doesn't make all of their own parts. That they contract other companies to run various parts. If a vendor could not supply a quanity on time, it was not uncommon to go to another supplier. That may or may not have constituted a number change or minor differences. Also, when they ran out of parts on the assembly line, they were not going to stop making cars until they got there. They would grab whatever was close and keep on chuggin. The whole parts ordeal was quite an experience.
