yeah, they look pretty easy to make yourself, i think its that cardboard-like stuff they make the package tray from.
no headliner pics yet, after i get another coat of paint on the car I'll get the headliner and windshield in, should happen within a few weeks.
having said that, there's not much that will be original in the interior, maybe door panels for now and the back seat. almost everything else will be tweaked or adapted from a different car, electric seats from a sebring vert, electric windows, and planning on making my own console.
