66 Plymouth Barracuda trunk panel below trunk

68 dart conv said
I’m working with a 66 Plymouth Barracuda and my question is the panel below the trunk and between the taillights is that panel the same between the 66 barracuda and a 66 valiant?

The 66 is the same panel used on the 65 Barracuda... and used on all 65 Valiants except the Valiant Station Wagon...
Mopar part number 2422 006.. see photo below of Mopar Dealer parts catalog... so I'm pretty sure that it would apply with the 66 model year...Hope this helps you..
