To replace the gas tank in a 54 Chevy wagon, I had to unbolt the shackles and lower the rear end. Shop manual said, “use a floor jack to raise the rear end to reattach the shackles” - lying bastards. The arch of the springs made it impossible. After a lot of cussing and head scratching, I devised a solution the guy above would like.
I put a rock bar under each rear wheel with a large rachet strap under bar. Then I lowered the car and watched to see when the springs stopped compressing.
At that point I wrapped the rachet strap and pulled the spring down until I could reattach the shackles. Sketchy as hell. :) But it worked.
