UK manufacturer of Cobra replicas with a backbone chassis is Gardner Douglas.

Much is made of the improved abilities of their chassis, although personally, I do not care for the shape of their body shell.

They do have a website where you can look at the chassis etc. url escapes me for the moment, but I am sure a quick google search on their name would bring it up if you were so inclined.

I have never noted any chassis flexing on my own car, which has a ladder chassis extremely like a Kirkham or Shelby, at least not in terms of door shutlines varying. And it does get some serious "stick".
