The tool doesn't fit due to limited space around the spring...so that option will not work

I already tried lifting the bottom with a floor jack...the problem however is that i can only get one side in IF the integral link is not installed; As soon as i install it, i can't get the ball joint to match with the arm.

Any ideas how can i remove that spring? I was thinking maybe i can put a scissor-jack between the arm and the frame and somehow push it down. Can this work? should I disconnect the shock absorber?
