Not bad.
If you want to keep it all Mopar, the later model cordobas used a mirror that has the exact same head as an E body mirror and has a through stud base, like the GM one above. They alos have teh advantage of being left and right remote adjustable. These can be found in yards for $20-40 a pair.
I've got a set on my Challenger. No one has pointed out that they are different, although I'm sure the hard core purist notice the lack of screw in bases right away.
