floor pan and cab repair, help please!!

[young.gun]

Hey guys I'm doing some body work on my cab from my 1967 small window 4x4 and the cab corners and rockers are shot and I know how to replace them. The big problem is my floor pan it is wrecked and rusted ill post photos tomorrow but does anyone know where to buy a full floor pan for a 4x4 with the detachable shift hump? Or I might be able to save my existing one with the patch panels offered online I just need some advice on what to do. Also would one of the 2wd low hump ones online clear my transfer case and such? And match up with my firewall? Anyone have this kind of experience?
