Can't get the rear beam to fit the bloody sleeve's inside the bush will not refit into the section of the chassis I have tried jacking in various points with no luck....

also to get the mounting plates back on it seem the bush will not to be compressed quite alot! I is almost like the bush is upside-down - even though the the profile is the same as the original bush I removed.... any suggestions - I have added this basic pic.... & yes I know I am shit at MS paint!
