Dumb question about wood 'burb floor...

[classicfins]

Hey, I'm new to these old 'burbs and was sitting here thinking about the wood floor in my '72. How do you go about replacing this? It's going to be a couple of days before I can get back to the shop to really get down and take a look at mine so I wanted to ask here. From my understanding the inner wheel well unbolts from the floor, but not from the main body, so I'm thinking the body has to come off the frame and then replace the floor?
