66 fender tag decode, think I have a clone

A clone to what? What do you think you have?

I posted this then saw your other thread. You have a 66 Barracuda that came with a 273 2bbl. from the factory. It is quite common for people to add the 4 bbl and Commando valve covers and air cleaner. It was also common for people to add this stuff new from the dealer. Either way drive it and enjoy it. These care are not a gold mine when it comes to resale and collector status, but they are also affordable for the average Joe.

The fact that it doesn't "match" is what I've been trying to figure out. Since it doesn't I'm not going to fret about tweaking and enjoying and personalizing it a little here and there. I try to keep to the original as close as possible but when I go off that...I go OFF and customize to the WT....that is cool.
I just want to make sure that "if" I go to sell I know that it isn't a true Commando?
