Rear end alignment question!
Daredevil, you want to be careful measuring from the center of the front hub to the center of the rear hub and using only that as a reference because depending on the alignment one front hub could be further back (or forward) than the other and it is quite common for this to happen. It is best to measure to a fixed point on the chassis, like a locating hole on the chassis and use this as a point of reference. Also you should use a point of reference on the suspension and not the wheel or hub because it could be offset in the car which would give you a different measurement from side to side. The best senario is to measure from the spring center pin to a fixed spot on the chassis that is the same on both sides of the chassis.
