Can't do it
Can't measure the shock via a picture. Tell her to take a ruler and measure from eye to eye, let all the slack out of the shock. (Take off the spring) and compress it 100%. Measure again from eye-eye and subtract that number from the orig. eye-eye measurement. This will give you the travel.
You will then have eye-eye and travel lengths.
This is the only way to measure the shock and get an accurate number. It would be even better to have a instrument that measures in mm, but you can get the US measure and them plug it in to an online conversion chart to get the mm.
