    These bolts dont appear to be removed with standard sockets. Are they metric? Do they require a special tool. I just want to use the right tool for the right job.

    12 point socket or box wrench should get you sorted.
    Don't remember, but it's 1/2" or 9/16"

    13mm 12 point will also fit but the 1/2" is just a wee bit tighter fit

    The guys have you covered above. Save those caps (at least one). They are handy for installing the new studs. Get a jam nut and run that on the stud's top end about 3/4". Screw the cap nut on to the jam nut and lock them. Use this to thread in your new studs. Loosen the cap from the jam nut and remove them once the stud is installed.
