it's a fooking nightmare and i doubt very much if you can do it on your own, i used some rope, got 1 side in and then with the rope pulled the other side in as much as it would go ( couldn't quite get the threaded end thru the whole but got it nto the 'cup' area) then just used a hammer and lever to get it all the way home. can't remember if this was with it bolted to the chassis or if that was done afterwards though??
