rear coil spring replace

[outlaw]

hey fellas, got a pretty easy question just want to make sure of procedures before starting project, I bought new rear coil sprigs for my 1970 chevy truck and was wondering if all I had to do after I took off the shocks was to use 2 floor jacks and pick up the bed until the springs fall out or is there more to it, I bought the springs but did not have time to replace them before I had to go back to work, thanks a bunch Danny
