Supporting an Fbody Shell

[grenade inspector]

I have finally gotten my 67 bird into my garage and started tearing the front end off for my build. without having explored too much I know that I will be replacing the quarters, rear valance, rockers and some of the floor/lower cowl. My question is, when I remove the rear and front sub-frame, how should I support the body? I intend to use at least some minor bracing welded inside the body while I replace structural elements, will simply blocking under the front sub-frame mounts and under the rear rails/leaf perches work? do I need to get carried away and bolt to all the sub-frame mounts and rear perches?
