Hi Paul, Unfortunately Morgan’s do tend to be a little asymmetrical but it looks like you might have lost some extension or droop travel on one side. Did you install 4 seater springs? I think if it was mine the first thing I would do is check to see the current state of the dampers and see if they were long enough on full extension (by removing the damper top fixings, jacking the car on the rear cross member so that the axle sits on the rubber drop stops and then check that the dampers actually have enough reach to be reassembled) as the stops should limit the movement not the dampers. Then if they were long enough and if they had some spare reach I would consider reducing the thickness of the drop stops (make some thinner ones) to gain back some extension travel.
Good luck!
