'65CJ-5 Body Drawings / Diagrams

I'm just starting to restore a '65CJ-5 which has good drive train, frame, and front half of the body (up to the dash). However, all horizontal sheet metal from the trans cover back is rust and most of that is missing, due to it having sat for 20 yrs in the wet Wisconsin weather full of rags, newspaper, and leaves. Does anyone know of a source (such as Ludel's) for drawings, diagrams, pictures, etc. which would show the components (hat channels, mounting brackets, isolation spacers) and their attachment points? The body is off the frame now, but it will be a long time before that part of the restoration begins and I want to be prepared. I know replacement body panels are readily available, but the support structure has me guessing.

 

The flloor plans already have the support structures on them, at least some of them do. The others are prety much a no brainer by virtue of fit.
