When I posted I didn't have time to mention,
When I arranged to buy the 78 series rear axle and the 200 parts, I met the guy at a mini industrial area unit just out of the emission zone in Birmingham. And the place was a container filling export place. I was early and was quite surprised by what was being loaded in. I was in my 81 and did pay the emission zone fine Lol.
I was blocking the car parking for the units and had to move to let a car out from the opposite unit and the driver said that they load all kinds and seen 4x4's loaded then all the boxes, clothes, washing machines etc etc.. It was an interesting insight!
