Since I have done lots of chassis work and repairs over the years, I looked for and got a very good ysed Hunter alignment rack that came out of a dealership that had to do the upgrade thingy(they will only update computer specs so many years and then---you need version h as your version d is no longer supported for upgrades---

also got a older STRING version 4 wheel sensor alignment that came from a Lincoln dealer that did the strech limo cars that wouldn't fit on the normal raCKS--

everything works great, reads out what you have and not what you don't have----

you can use any specs you want and the computer has the specs up to 2002 stored in it, just the printer is an old version parallel deal with ribbon ink that you can't get stuff for and can't update op system for drivers for new ink jet stuff--

but the rack, turn tables, jacks allow me to mock up, trial fit for full travel, etc and after finish welding can do the alignment all in place


Isn't 1/4 degree of caster pretty unstable on a real road????
