Replacing upper control arm bolts

STOP!
The New bolts may not have enough threads on them, and when you install them as per the directions, you will torque them up and think that they are tight, but they can come loose at any time. Twenty years ago, I was an alignment tech, and got fooled by this exact thing. Don't let this happen to you!
My solution was to procure some 1/8 hardened washers and install one under the head and one under the nut; problem solved.
