I hope I don't get "flamed" (pun intended) for showing Ronnie Spain's GT40P/1069 report. All kidding aside, GT40 monocoques are extremely strong structures. Several cars have been "toasted" and lived to race another day. If a GT40 was street driven in the UK for decades, a bigger and more prevalent concern is: rust. Given the right shop, that too can be remedied.
