jhubbell: I have the exact same problem with my '58. I find that the step where the 'flipper' tucks tight under the deck lid is extremely sensitive to the state of battery charge. For me, it won't tuck all the way up if the battery is a little low, even if the car is running. I charged my battery to 100%, and tried it with the engine off, and it worked fine. I hope it's that simple for you.
