I was browsing ebay when i came across these:
https://www.ebay.co.uk/itm/Superflex-Fr ... 1438.l2649
They look very,very similar to MGZS Rover 400/45 parts but without having them next to the original parts not sure they will fit,

1234Dist is the man to ask; but at a guess I would say no, because a 600 is a much bigger car?

i did answer this back on rovertech ( )
No they won't fit but superflex do the bushes for that car anyway.

Thank you but it was the stainless bit that caught my interest.
