Your ONLY accurate way to measure shocks is to flex out one corner, and get to measuring.
Remove all 4 shocks.
Drive a front wheel up onto a ramp of any kind, until a wheel starts to lift off the ground. Something like this (excuse the Heep)....

Park it and measure the distance between all the shocks upper and lower mounts. This will give you the open and collapsed measurements for the front and rear shocks.
