Terry,
Emerson redesigned the door hinges and he got an extra 6" of leg room by cutting away the part of the sidewall that the hinge used to be behind and moving the cowl bar a little. His design works great and that extra leg room makes it much easier to avoid the hot pipes when getting out. I had talked to Bill about upgrading my doors before I sold my Cobra. He has done a lot of improvements on the cars he now builds.
