Like you I also had a '57 Ford Convertible. I used the AMT '57 Ford Fairlane hardtop kit to make a model of it. I cut off the top. I used the Boot from a later model GTO, I think it was the AMT '65, and displayed it with the top down. I have never found anyone making an Up Top for that model. I might also be interested if someone knows of a current caster of an up top for the '57 Ford.
