65 Barracuda - Advice on where to get stuff - door trims, carpet etc

There are members from Europe and your neck of the woods who make arrangements with a shipper? They rent a sea container and when they buy stuff have it sent to the shipper who puts it in a container. When the container is full or has enough the shipper sends the container to the member.

As for seat covers door cards etc. legendary auto interiors has become the industry go to, BUT, others sell their stuff as well.

I'm thinking for what the sell for plus import fees and shipping, you might be able to have an upholsterer in your neck of the world copy your existing seat covers etc and it might be cheaper or at least a wash.
