A while back I purchased the upper deluxe rear seat filler panels on E-Bay.It was a great deal because the guy sent everything including the original ashtrays and the lower panels that the ashtrays fit in.The lower drivers side panel was in great shape but the passenger side was really rusted out.I looked it over and decide to make my own.I cut a piece out of a 2003 Dodge Ram hood hood and this is what I turned it into.It turned out great,all I have to do is make 2 spot welds and its done :D

By the way I won the auction for 15 bucks :D .
I know I could have bought a new panel for about $50 but I had to try making one anyway.
