Re: 1955-1956 2 door
I owned a 55 Ford convert back in 1960, but I guess that doesn't help much.
(My first convert and real "drive-in" car. Bought the car with my high school prom money.)
Unfortunately, after I bought the car (for a whopping $425), while driving the car home, my buddy pulled along side and said, "do you know your car is going down the road slightly sideways?"
Never really could shut the passenger door. Door kept flying open on any bump.
After three months, fair swapped that car for a 54 Olds 88, 2 dr sedan, three speed column shift.
The Olds had a heater that worked, and the doors stayed shut.
