Hey Hyper-Pak - is that the inside of a 61 & 62 Lancer wagon? I ask because the cargo floor 'board', grooved seat and shape of the rear windows look more like a 63-66 A body wagon. The floor of the cargo bay in my '63 Dart wagon has that big floor panel with dish and wing nut to hold it down on the spare underneath.
Yep that is my 62 Lancer. Wood board goes all the way to the rear sill. 2 metal panels on either side of the wood board. There is a hole with a metal plate and a wingnut holding it all down. A metal plate over the shock mounts that goes to the back of the rear seat.
