stock type adjustable rear suspension?

[tt69camaro]

I had my first day off in three weeks today so I looked the car over and low and behold the passenger front spring was out of the bucket. I put it in correctly and now the car sits 1/4" high on the drivers side but I can live with that. Anyone know how much the spring will settle and how long that will take? Do the rear spring settle much? Thanks again for the replies.
