need a under 3rd seat panel AKA Trunk panel. I looked a couple places and they only have smaller ones for a sedan and coupe, and I have a wagon LOL . any advice will be greatly appreciated.
It is doubtful that anybody makes a new panel for you. Your best best is to either fabricate a new panel or cut a good one from a donor wagon. Since these are prone to rusting due to water collecting in them a good one may take some searching to find. You could try some of the junkyards in Arizona that specialize in older cars.
