laguna rear bushes with a nasty twist

so i finally had to do the rear bushes on my laguna 2 estate

i'll be honest i've been avoiding it like the plague but i had no option because its mot time on monday (well it was)



firstly i read the haynes ....... not really that much help tbh



then i searched here and found lots of help and information



i did the bush on the drivers side no problems ....took about 45 min



then i moved on to the passenger side and it all went wrong

not with the bush replacement ....i've done that and the car is all back together ....no what i found on that side is lots worse than just a worn bush



the top mount for the shocker has broken away from the car ...... at least now i know what the clunk on the back was the other night



right now i have very little idea how i'm gonna fix this .... ive had a chat with renault and they dont make a repair panel in fact the guy in parts didnt actually believe me untill i emailed him a pic of the broken part



it looks like i'm going to have to find a dead laguna in a scrap yard and cut out the bits i need



has any one else had this problem or anything like it ??
