Was unable to put on the new box but I'm taking Fifi for her MOT on Monday & they'll fit it afterwards. However, the new tie bar bushes are on. Was unable to document it however. What I can say is that the old ones are made of this weird sponge & the reason Fifi was knocking was that on the offside, one of them had actually disintegrated!
Changing them was actually relatively simple & straight forward. the design of the bushes also eliminated the need for the horrid plastic "bearings". The car though still feels nice & the knocking noise is now a memory
