Need Help - Wheel alignement settings for new style "camera" eqipment
Ok, so please read carefully so you all get this right :-)
The wheel alignment places in this country (UK) have moved away form the traditional laser wheel alignment equipment (where you put a sensor/electronics) on each rim then aligned the front end and compensating for thrust angle etc.
These days they use a camera equipment and only put a flag if you like on each rim (so no sensors and no electronics attached to the car/wheel at all as the cameras do all the work) and this means they need initial data for the rear end settings (toe and camber) to be able to set the thrust angle and do the front wheel alignment correct (per my settings for toe,camber,caster).
So the BIG question is what should the toe and camber values be for them to enter this into their computer for the rear end?
And yes I know we don't adjust the rears as it's a stiff axle but they need these values as it's the reference for doing everything else (so they don't use it for any rear end adjustment but need it to have a fix for the thrust angle etc.)
So if any of you guys work with these new camera (so not laser style) wheel alignment equipments what is the values for the rear end for a 1989 Trans Am??
Even if the machine is US made there's no data in their computer for the 1989 TA's .....
So any help would be much appreciated as I need to get the front end aligned after my rebuild.

G()d help you. What kind of BS is that over there. It must be some kind of transit type camera registering distance. How on g()ds green earth to you square the rear first to then square the front. Front is fixed for the most part when it comes to doglegging thrust angles. You basically measure the rears off the front (you can do this primitively with a tape measure and a buddy). Very long straight edges work well also. We use those in NASCAR to measure outside wheel track making sure the outer wheels are in the same path.
I would just have them imput a generic reading with considered tolerances of stock rearends to be built neutral to slight toe in, and the camber to be built neutral to slight negative.
toe- 1/32" in
rear camber- neg .15
