bad news, but i couldn't understand if you changed them or not....
if you didn't, please send me part numbers or anything else (photos, designs) of the part so i can search for them. i have an excellent guy in spare parts who can help, and i have already spotted 2-3 espaces like ours in spare part shops. so there is still hope!
so if i understood well and you are still searching for these bushes(!)... (this is really funny for me as my mind goes to completely a different thing....) please provide any information you can.
really sorry but English is not my native language and car parts is a very difficult subject to translate
