1966 Plymouth Barracuda - Commando 273 V8

@Commando66, it is! When I first looked into it, I was astonished to find out they actually made base/non Formula S '66 Barracudas with a Commando 273! It does have the fender tag, says 32 under the second A-Z/AB row!

Thanks SSVDP! I got lucky, previous owner found the rocker trim panels for it, but is still searching Mopar heaven in his garage for the trim rings, so hopefully those will turn up soon!
