Hey Frank good to hear from you and really good to hear you got another Cobra, you said you would. The center line measurement fore and aft is 13-3/4". The rear hole is very much a half round end rectangle because of the angle. As you know with cars like the Contemporary they did the short rollbars on quite a few to fit under hard and soft tops and that made the rear brace hole way far forward for original style. That makes it hard to get a correct looking rollbar without doing bodywork on holes but I have seen some careful bends put in rear braces to accommodate different height bars.
