The AM GT40s must be some of the rarest ones...would you mind a few questions, I'll try not to make it too many...
Do the AM cars have aluminum or fiberglass bodywork; I recall reading that to make them lighter they had aluminum bodies? Also, I understand these cars had changes made to the suspension pickup or mounting points which made them handle better. Is that true, and if so, is that data or those changes reproducible on a monocoque that would be built today? How much of a difference would it make in handling, do you think?
Also, pardon my ignorance, who is Alan Mann and how come, in all the GT40 books and articles I've read, there is never a quote from Alan Mann and never a photo of him? Is he unusually reclusive or (regrettably) no longer alive? It's a bit mysterious; everyone else seems accounted for one way or another. Maybe I just haven't looked hard enough.
Your GT40 is a real piece of history- good on you for keeping it up so well and good for you to have such a unique car...
