Now let me see if I can get this. You are having a problem with the rear
settling and can't get a good reading on the camber and toe after it is
jacked up. Now I have never had that problem when I did the 250 and some
6's on my rack. Had a 4A IRS also on it and no problem. Did the guy slide
the rear plates all the way in before leting the car down. An alignment
rack should always have free moving plates. If it done it on your car just
imagine the new Buick LeSaber and Park Avenue they really slide the rear
plates out but you have to slide the plates all the way in to keep it from
coming out to its maxium(plates that is). If this guy done it on all the
new cars with independant rears I don't want to even think about what he
tells all those customers.
        The readings that my FMC book gives 1/2 deg. positive camber for the 
and about 1/16 toe in.this is without weight. The rear it also gives 1/2
positive camber and 0 toe.
        Hope some of this helps.
