67-69 vert rear seat

Rear seat frames from verts are often quite rusty, especially the bottoms. Not rusty wont be cheap. Bottom frame from some other, like notch back, is a materials donor for restoring a rusted vert bottom frame. Sebring seats would be most affordable route.
I'm looking at the pics above and wondering could that bottom frame be modified to clear the hump, fit better. It probably isn't made of much. Most newer seats are just molded foam on a wire frame, no springs. Good luck to all.
You are correct it is just basically some foam and wire. I just threw the seats in there one day to see how close they matched up to the side panels. There is not any mounting provisions in there yet. Back is just propped up. I cut out the bottom mount from the Sebring along with the rear that contains the shoulder belts with the plan to use some if not all to install. Just haven't made it to the floor/ interior side of the metal replacement yet
