Issues of frame mods were the reason I bought a Hunter alignment rack-as the vehicles were getting longer-stretched suvs--the shorter older systems that used strings, etc instead of the fancy new shit became real cheap-I got one that had been in a caddy dealership that did a lot of streched limos but they upgrated to the newer system-------

It sure works nice to be able to move major components and keep the suspension correct instead of making a big move and then working your ass offf trying to correct bump steer,caster, camber , wheel base, travel--------
