Ray, with time the chassis can get a bit tired and start to flex, binding of the doors is not uncommon, but the reverse of the coin is that the door gap can open up. My first Healey , a 100/6, was prone to throwing the passenger door open on certain bends as the chassis flexed. The body was refurbished by John Chatham and they straightened out the chassis, as it had become distorted over the years, by chaining to two ends to the ground and jacking up the middle and with a little re work on the door posts, new floors and wings, it stiffened up the framwork and the problem disappeared. It could be that you are suffering from a tired chassis, though it is fair to say that the cars do flex anyway.
