I cut the wiper spines through as they were well knackered and were fused to the wheel box stem that just cost me $300 from land rover, thing is it is a major mess up on the Defender and so probably happens with a frequency that keeps them all employed and happy......so why so costly i was amazed at the cost of my must have items.
p.s. I tried everything F.B.H, heat, loads of rost off ice to no avail what a painfully expensive learning curve
