Been doing a few jobs to this in the past few days.
First up was to delete the rear wiper, the wiper was not adjusted properly and went clear past the body. I bought a cheap wiper cap. A tad cleaner with the body lines.
Then removed the 1kg weight in the boot lid
Bought new kidney brackets and hardware and got rid of the slash shield which was an advisory on the last MOT. Brackets were solid still but I wanted to underseal where the brackets and W brace attach to the chassis.
Used Rustins rust remover then treated the areas with rust converter then washed and undersealed the areas under the arch lip, tubs and mounting points
Much nicer now
(I used axle stands and only used scissor jacks as a back up in case you spot that)
