It's going to be pretty much the same. On my 70 300, the top goes up and then folds forward as you describe.I found a video of the top retracting on a 1967 Fury. Is the mechanism basically the same on mine? I ask because mine is up and not functioning and I want to lower it manually. In the video it looks like the entire top cantilevers up until nearly vertical and then it accordions up. Thus, you wouldn't start by lifting directly at the front.
Unhook the cylinders and it should go up and down pretty easy.
