I understand that there is a forum for just restoration questions, but I'm not a member as of yet so I was hoping for some basic info here. I have an 85 K5 and it's needing various replacment sheet metal due to rust and rust holes. I've seen replacement parts where you cut out the rusted part, and weld in the replacement part but I was wondering if you could just unbolt parts off of say....A junkyard K5? My first replacement needs to be the bed and floorboard. Can I just unbolt and replace these parts or do I need to cut out the rusted places and weld in new metal?
