  1. Hello,
    I have an early Series 1 4.2L OTS. My jack is of the correct type according to your info and appears to be the original for the car. Except it’s painted black like the one in your picture above instead of grey. The paint is old and worn. It has the attached handle with a clip on the end. I have 2 questions.
    1. Is there supposed to be a washer under the circlip holding the handle on?
    2. I have a grooved washer that appears to go inside on the ball bearings that is broken in half. Do you know where I can get another replacement?
    Thanks, Ted
