Rear replacement bushes I got cloned in urethane 90? I can't remember or 85.
To install them remove the top mount bolt, you might wanna hold the shock with vice grips to stop it spinning. I put vice grips on the shock piston underside.
Take the top mount bolt off.
Jack up the rear, slowly (so the spring doesn't fall out).
Remove the bottom strut bolt.
Torques can be seen here on the right. Bottom bolt was 100NM and top was 23NM.
Old with the new.
