• If it has a LH thread, then it originally had self-extracting bolts.

    Couple of different types here (towards the bottom of the page) for around a tenner.

  • Thanks very much for the information ,
    I didn't explain the problem correctly . I have been able to remove the bolts but the left arm is stuck to the bb spindle. The crank puller that I have, removed the right drive side but won't remove the left side because of the different thread and this thread is for the combined dustcap and bolts . You can buy left hand thread Campag crank puller but these cost a fortune, and was wondering if there is another method to remove the crank arm.
    Sorry for the confusion
