73 Passenger side remote mirror

[centurion 455 ragtop]

Its not mine and kinda steep on price, but looking at it it does match up to the 1973 models. I also checked my books and there was an optional remote passenger side mirror offered. The remote part is mounted under the dash to the left of the ashtray area. I have never seen one mounted up, but this is the mirror if anyone is interested.
