Back seat elimination

I too don't have a good picture of my 64 Dart rear seat removal.I removed all the seat brackets from the floor and backrest area. Went to Lowes and got 3 sheets of aluminum and made the package tray and down to the floor.Then sprayed the complete area with truck bed liner. The car was built to be a rat so that is how I left it.You may check and have a upholstery shop rug the area too.I have also seen it in fabric and vinyl to match the front seat cover pattern.
