+1 , you'll want to try and outer part of bar parallel with the ground, you'll just need to cut sleeve,and get a shorter grade grade 8 bolt, i just installed front and rear bars on my lowered 91 Burb last year. I had to do front the same,and also used lower standoffs to frame brackets. Huge difference, next is good adjustable shocks.

BTW the rear bar follows the contour of housing,bar mounts under the rear axle, you'll need to drill holes in frame for rear links, mount bar to rear-end, and then swing it up and mark holes for links,measure the new length for end-link bolts, and drill, deburr,mount end links, torque bolts. don't forget to use synth. grease on sway-bar brackets. don't over tighten,you do not want to squish bushings.
