Spring Removal/Cutting tips??

[cr34t3d_by_d4rkd3n]

Hello everyone, i come to you guys today with 2 questions:

1) Has anyone removed a coil spring using a jack? I know on the Buick's u can slowly lower the lowers's with a hydraulic jack, and the spring will fully release tension, and safely fall out.....
____-what about these trucks? can you do the same or will the spring slip out of its pocket and become a missile? haha

2) USING A CUT OFF WHEEL how muck spring have u guys removed to how much drop you can get??
ie: 1" of cut coil=7/8 drop

Just trying to prepair for my over haul.... staring in 2 weeks !!!

THANKS!!!
