Please identify this '70 'Cuda rubber gasket

Not sure what this gasket is called or where to find one (vendor)?





All I can seem to find is the fuel filler neck gasket thats back by the tail panel.

Thanks

I don't know what is going on there exactly, there appears to be an extra piece sandwiched in between the vapor separator & the trunk floor... There should be the vapor separator, a foam gasket which Jim makes & then the trunk floor...

This is all thats supposed to be there

Is that a Calif car?? 49 states had a much smaller vent tube.

Thank you guys!
The pan & extension are gonna be replaced shortly, so I wanted to make sure I had the right seals.

Also, yes, this is an LA built 'Cuda with ECS.
