    Wow! Mine were always real greasy from the British external lubrication
    system. No chance for rust to get started when metal is protected by a
    thick layer of oil.

    As far as I know you just get them out any way you can and replace them
    with new pins.

    >Any tips for clutch replacement would be appreciated as well.

    Since this sounds like the clutch has been ignored for a long time may I
    suggest you take a good look at the clutch linkage between the clutch
    slave cylinder and the throwout bearing. Parts wear over time, holes
    elongate and slop is created in the linkage.

    Just a little slop in the lower linkage requires a larger amount of pedal
    travel to take it up. Add up the slop from a bunch or worn joints and
    you can end up with a lot of pedal travel just to take up the slop.

    When I checked mine, all the holes were elongated, the bronze ball was
    badly worn and distorted and the felt pieces were almost gone. I ended up
    replacing the collier, brass ball, 'L' lever, felt oil rings and pins.
    When the old parts were in, the clutch released less than one inch from
    the floor. With the new linkage parts and no other changes the clutch
    released when the pedal was half way to the floor.

    Now that I think of it, I wonder how many people ever periodically add a
    drop or two of oil on the felt pads around the brass ball on their clutch
    linkage?

    ??????? The relay lever for the clutch on a series IIA is beside the bell
    housing under the clutch slave cylinder. That is way far from any stock
    fuel tank.

    Any chance you are referring to the emergency brake linkage? If you are
    referring to the e-brake linkage, and the lever that is mounted to the
    inside of the frame you do not have to move it. And you can get to both
    sides of the bolts without removing the fuel tank.

    As I recall around 100 pounds, probably lighter. I just get in there
    with it, pull it back and let it rest on the transmission cross member
    with a jack stand supporting the rear.

    Speaking of which, do not forget to put a jack stand under the rear of
    the engine to support it.

    If you have not done this sort of thing before, follow the factory
    workshop manual closely. It will be a lot easier the second time.
