Were there any major differences with the Cossie shell over any other Sierra in terms of rigidity. I know the RS2000s had the gussets for strength.
I would be interested in that and ideally the new shell would be from another cossie donor if so. Sadly the classic car world is obsessed with originality for the top money. Personally it would not be important to me unless I was paying absolute top money for something to be original and then to find it was not.
