Well, I 100% agree that I am going the wrong way - I seem to be too thick to solve this one!Hawk, I think you are going the wrong way with the shims. You moved the back of the trans down, then you moved the nose if the pinion down, making the relative angles the same. Try leaving the trans the same and go the other way with the pinion. Worth a shot?
I agree that could be a possibility. However, I am going to try and do some careful driveline angle measurements so I am not guessing my way forward. If that is not definitive, then I can certainly turn the shims around and see what happens.
