I have a 1985 toyota pickup and I want to lift the truck using the springs that I have. They are toyota rear springs and chevy 63's. Questions like how far do you move up the spring mount for the 63's and what size square tubing do I use in the front for the rear toyota springs.

For the chevys we put the spring hanger 11'' forward from the original hanger then measure from the center of the bolt hole in the hanger back 61.5'' to the center hole of the shackle hanger. This gives you a good shackle angle.

thanks for the info
