    Bent Rear Caliper Guide Pin: Replaceable?

    Hey guys.

    I just received a set of B7 rear calipers, and I thought I would take them out of the box today and check them out. One caliper looked just fine, other than a bit of rust and some wear typical wear. The carrier and the caliper seemed to slide relatively well, there was a tiny bit of grinding but nothing that seemed out of the ordinary or that a bit of TLC and grease couldn't take care of.

    The other one was a different story. It seems to have been bent where the caliper slides on the carrier. Basically the guide pins are bent. Do I have any options for replacement of them? Is this one of those cases where the fact that the caliper has seen enough force to bend it like that means the caliper is probably toast? I paid $60 for each caliper (carriers included) so I wouldn't be super upset if I needed to return just the one and stay on the hunt for another one.

    The bend is barely noticeable. I didn't see it until I was trying to slide it and it wouldn't budge.

    What are my options here I guess. I was planning on fully refurbishing the brakes before I threw them on and I'm not in dire need of rear brake replacement so waiting a bit for rebuild parts isn't a big deal. Is it even possible though?

    Facts:
    --They are B7 A4 brakes, keep that in mind, but plenty of people on here would have these brakes and the B7 guys would probably not be very helpful.
    --Only one of the calipers appears to be damaged. The other seems fine.
    --They are rear C41 calipers (288mm rear rotor size).

    Edit: Will this bolt set work?

    Also one more question: As far as the refurb process, I was thinking of this for my order of operations:
    1) Clean rust, crap, off caliper with wire brush
    2) Soak in rust remover
    3) Rinse/Dry thoroughly
    4) Paint with engine enamel or some sort of high heat paint (black probably)
    5) Rebuild, including new seals
    6) Install
    7) Profit

    Any thoughts or objections?
