Droop

[bald eagle]

Am I correct in saying I may have to change the front gearbox top case if the droop isnt the same both sides? The shocks look to be uneaven in length, but if I take them off the car and measure them, they are the same length. I have done a small amount of research into this and it seems that some case tops are not as accurate as they could be in the mouldings?
As always, any help is greatly appreciated.
