Lower rear panel removal

[jlmerie]

I am looking for some help removing the lower rear panel from a 1972 Suburban with the tailgate hinges in it. I am going to help my buddy this weekend. His Suburban has a damaged rear panel and he has found one that someone is parting out. The problem is that it is out in no where so we will only have hand tools that we can carry with us. What is the best way to remove the lower rear panel from the donor truck? This is a bolt in, right? The plywood deck is still in the Sub, but we can hack into it if we need to. Any suggestions / insight would be appreciated? Thanks
