Welcome aboard there 73!! You can make yourself at home here, lots of good people and info!! Pics are a plus and maybe a pic of that backseat for a little visual on what you're dealing with !! Geof
Welcome aboard. Like Geof said, pics are always helpful. Also, like Adam said the Service manual should have plenty of diagrams for you. I believe there is an online download for it, but for the life of me I can't remember where. Maybe someone can chime in with where one is located online.
