The shackles may be very difficult to get out depending on their condition. Be careful with the spring, it has a lot of power stored in it when under tension. If you need to take the spring apart there have been several threads on that topic.

JSeery has offered great and accurate advice. To reiterate in part of what he advised... be careful. Springs hold a lot of pressure. I did not look at the link he'd provided but will caution you against using a home made spreader out of any type of threaded rod. Yep, many guys have used it and it has worked. However, a few guys have used it and gotten hurt. Threaded rod is NOT designed for this type of application.
