We like to do the drive shaft real close to last, Denny's can make them in no time so wait till your almost done and everything is mounted on and in the car. I like to have all the weight in a car and lifted by the wheels to make the measurements. Real important things like this measurement need to be done just as the car would be going down the road. Find a way to lift it buy the wheels, I use old alignment tables but what ever you use do it safely.
