See
this thread for OEM '88 alignment specs. You will see that there is no explicit spec for thrust angle, probably since thrust angle is just a by-product of rear toe and which can be defined as half the difference in toe between the two rear wheels. If one rear wheel were aligned at the lower toe limit (0.05 degrees) and the other rear wheel were aligned at the upper limit (0.25 degrees), that would result in the maximum possible in-spec thrust angle of +/- 0.1 degrees ... i.e. thrust angle = (0.25 - 0.05) / 2. As
Bloozberry correctly stated, you always want the thrust angle to be as close to zero as possible.
