I have an idea involving some intense bodywork for a kustom to do sometime far far in the future with my f-body. I'm wondering what body panels are truly integral to the unitized chassis?

1. Floors
2. Trunk pan
3. trans tunnel
4. firewall
5. rocker panel
6. a pillar
7. b/c pillar
8. rear quarters?
9. structure behind tail lights?

If any aren't load bearing, let me know. If I missed something, please let me know. I'm trying to figure out which body work will be metalwork and which can be done with composites.

Thanks

 

AFAIK, a unibody constructed car relies on the whole thing for integrity.

 

Its safe to say the anything made of metal is "load bearing", and anything made of plastic/composite is not.
