Which panels constitute the 911 monocoque shell?
 

Hi folks, I’m hoping your collective knowledge might be able to help me please. In the UK the DOT and DVLA govt departments are obviously very keen to know to what extent a vehicles Monocoque shell has been modified or restored for the various tests they perform for roadworthiness and safety. I’m keen to establish which parts/panels Porsche themselves actually consider constitute the monocoque shell. Do there exist any drawings or diagrams that describe this?

Specifically I have a 1982 RHD 911SC Coupe.

Thankyou for any thoughts you might have :)

Hi Motley911, id be interested where you sourced the diagram you posted above, I’m looking for something similar for my 1982 911 SC coupe. Does it come from the Porsche workshop manual?
Thanks

UK M.O.T. ?
That standard is up to them, likely based on specifications and alignment of the tub corner to corner. Inspection would be flagged from the underside based of appearance of alterations, expanding further to welds on panels including interior. Being a “single tub” unit that is just about everything.
US have completely different approach to rebuilds on salvaged title of registration.

Not sure if this link describes what you need. Check this post out from a Pelican -

Well, the tub is usually minus front fenders, doors, engine and trunk lids, front and rear bumpers.

Ultimately it’s what ever the UK determines part of the structural chassis.

Thanks EC900 & 70SATMAN much appreciated. I think you’re right the DOT will deffo make their own rules and thoughts, so I’ll do some research around that. Im also heartened by the thought that the Tub list above is what I think the monococque structure also is. Many thanks.

probably more than this, but maybe: (I really like this photo for understanding the chassis build)

and the whole unibody tub, (not a monocoque technically), at the factory:
