65-66 Barracuda inner trim for the rear window,
The 5 parts you are making are the sought after parts that crumble over time! And maybe if you had enough interest the correct plastic body plugs to fill the center trim access holes. I believe any correct size plug will fit but design was different. Alot of guys stated their cars didn't have them. Maybe the factory, ran out, got lazy, they fell out, maybe '66 only or maybe '64 '65 and someone put them in my '66.....who knows!!! Maybe even the factory stopped using them in order to stabilize and release heat from the back window / rear cargo area!
I have seen another Cuda with these. What made more interesting it had a blue interior. So...the 4 interior parts were blue and so were the 4 body hole plugs. All matched in color.
