Mini tub fastback pics anyone?

I have a fastback and have always wondered how it could be done. I know it can be done but what mods would have to be done to the interior panels that are located in the cargo area? I mean is that area even affected? The panels on each side are against the tubs. Sorry to but in 68383GTS but I'm very curious about this myself. I mean I have friends tell me to tub mine but I tell them that more than likely it will affect the cargo looks in which I really don't want to do. The panels attach to the body at the top so moving the panels inward would make it a PITA to re attach them along with the stainless trim .
