I was hoping someone here could help me with the specs on the rear bulkhead (firewall) window and frame on an original GT40 MKI. On the frame I’d like to know its height and width. I also would like a picture of how it sits on the bulkhead so I can see how much gap there is from the roof to the top of the frame and if the opening in the frame is the same as the bulkhead. If nothing else one good picture of the window would answer most of my questions. The car is so low that every interior shot I’ve looked at so far doesn’t show enough of the window to be of any help. Thanks for the help.
