I diy'd them, they aren't easy without a press and puller, I burnt and cut the old out.
The rear bush knocks in with a socket resting on the outer shell, the front was a little trickier, made a plate with a hole to rest on the outer shell one side and a pipe around the other side of the arm, trapped it all in a vice and they popped in.
You could remove the arms, burn the rubber out of the arms, thread a hacksaw through the holes and nic through the outer metal shells, two careful cuts and they drop out.
Then fit polybushes, they just pop in with a bit of lube, a forum member sells them Poliurethane Bushes | Facebook
I'd have fitted them myself if I knew at the time.
I'd say 2.5 hours doesn't sound unreasonable for a garage to do them though.
