Whats involved in putting a 2\" body lift on a 93\' Z71? My dad has a '93 Z71 and it's already been lifted a little bit (not really sure how or even if it is a true lift or just torsion bars, but it's deffinitely not a body lift), it runs 33x12.50 MT Baja HP's with just very minimum rub. He wants to install a 2" lift to give it a tad bit more height. Is there anything I shoiuld keep in mind while installing the body lift? Tips or tricks?
