New rear leaf springs - installation?

[rbohm]

first get new front spring bolts and new shackles as well. you may have to cut the old bolts out. if you do use a sawzall. you should also get new ubolts as well as the old ones may either break or need to be cut due to the nuts being rusted in place. also use lots of penetrating oil like pb blaster. when you put th enew bolts in place, lube them with wheel bearing grease first as it will ease installation, and future removal. dont torque the bolts to spec untill the car is on the ground and you have bounced it a few times to get the springs to ride hieght. also remember to drive the car for a few months before you change the ride hieght as the springs will settle some(about 3/4"). if you plan on using lowering blocks, make sure the u-bolts you get are long enough to allow for the use of said lowering blocks.
