I knew that installing my car lift would be a boon for really seeing the truth under my 240. For years, I've laid on concrete in the dark trying to get an accurate picture of its condition. What I was surprised to see in the light of day was the rear control arm on the passenger side oriented so that the 'concave' or 'recesses' are facing down. The drivers side rear control arm is oriented in the opposite fashion - facing up. Is this 'Datsun design' or a mechanic's Friday afternoon special?
