Doing a convertible conversion is always a fabrication problem because of strength reduction. Even on a frame car like my 57, removing the top will allow the car to flex more than normal. On 57 Convertibles the frame has a large X member that is not present on the 2dr coupe. You situation is even worse as the 67 is a unibody and the roof is definitely part of the frame. There is a guy in Atlanta (drivers seat investments) that sells a convertible conversion for early Mustangs. Also Unibody. He spent a lot of time and money engineering strengthing braces to change the hardtop 'frame' into a convertible 'frame'. Four doors is even worse. Building a show car with a convertible or lift off 'carson' top is one thing but building a driver is something else again. Nothing is impossible Tristan but I'm not brave enough to try it and I'm pretty brave when it comes to fabrication.
