Coil Spring Help

I just purchased a leveling kit for my 89 full size. I removed the old coil springs and shocks rather easily. Now, I can not get the new springs compressed enough to go back in. Am I missing something? I currently am working on the drivers side. Will I have more room if I remove the shocks and springs from the passenger side too? I have tried 2 different spring compressors, and still need an additional 1.5" to get the springs to fit.

Thanks.
