You're right, I don't know. Didn't say I did. I still stand by my statement that Chrysler was often "cheap" or in other words economical with regards to mass production - and doors are no exception. I think hood pins, rear spoilers, and hood scoops are in a different class of options. Every car had to have doors but not the latter. They were add-ons.
Do non-remote mirror cars not have the hole drilled for it? Have you seen factory sport mirror cars with the mirrors farther forward?
