Early A Convertible rocker

Right now just fishing for some information on the rocker area of the early body convertibles (1966 in this case). You can see in the picture there is a decent amount of rot right about where the back of the bench seat ends and the rear seat floor well begins. (Other side looks “better”)

I’m eventually going to cut this open and see what horrors await but that’s a winter project I think. Does anyone know where I can find more information on this area of the car? Parts fiche?

My research so far tells me the metal is thicker here but I’m curious about internal geometry and eventually the process I’m gonna need to follow. Currently I’m planning to get the front pans replaced and add subframes before I hack into this. Thoughts?
