Metal inner panel that is spot welded to the support brace which is not included in the shipping price. This panel also makes up the rear glass side inner area that tended to rust out with your channel. Price is $100.00 and shipping is $30.00. I should have the other side. There was an extension piece welded to the brace also to make the shape different for the 68-69 and 70-72, I have those too for 25.00 each, there are two per side(one shown in last pic) all 4 for 80.00.
