That's true, but, I didn't have the spring sitting in the pocket properly up top. The spring was sitting on the rolled lip of the hole punched through the frame that forms the pocket. All I had to do was pry it off of that lip and it fell right into place. I didn't have to rotate the spring at all.
I just stuck my hand in between the upper control arm and the frame so I could feel inside the spring pocket. Sure enough, the spring is not in the pocket. It is sitting off center on the lip. Ugh. My Saturday morning project will be fixing that instead of installing my new rear brakes I guess.
Those d**n springs are a pain. I have a thread here about that when I changed my engine to a 455... difficult to do in a driveway...
