71 Demon remote mirror ??'s

Hey Mike, swap meets and ebay, the same bezel was used for both styles of remote mirrors (sport/rallye). You will likely need to by a complete mirror, as finding the bezel separate will be difficult. Hopefully you can find a loose and pitted mirror for cheap.

The bezel on the right hand side is the one you are looking for (P/N 6027749).
By coincidence the bezel on the left is a 2999001, I believe for '68 Barracuda.
All the best!
