Rear Spring Question

[baking]

Just put some new springs on my 70 Skylark for the rear. After putting the new springs and new shocks on, I am able to turn/wiggle the springs by hand with the car up on a lift and the rear axle hanging down. Should they be able to be moved like that? The place I bought them from and a coworker of mine said it shouldn't be a problem. However, I would like to know your thoughts on if this is safe or not. The old springs were about a coil and a half longer and still fit tight when up on the lift. I don't plan on doing any Dukes of Hazzard jumps, but I want to be sure these springs are not gonna pop out if I hit a bump or go over RR tracks. <BR>I haven't been able to set the car down and see if it sits level, because the axles are out because the differential got pooched which is another story.......
