I did my cab. Fairly straightforward just make sure you get a bag of the anodised black screws that will need replacing and the "C" clips that are in abundance. Just check the parts catalogue for what's needed.
I removed the rear bumper and also found that the aluminium brackets that hold on the crash bar were shot and if ever I'd been winched out by the rear tow eyelet, it would have pulled the whole lot off the car. The heat shied was shot but repaired with some silver highly reflective tape and the bumper brackets were replaced with some I made from stainless steel using a tube bender and a friends hydraulic press. As for the caked mud and rubbish stored at the back of the wing over the years, once it was removed with a pressure washer and well dried in the sun, the rust was treated with POR15 and then wax oiled. Not seen any rust bubbles since.
