Buy a service manual. It will be the best $60 you have spent. Even if you only use it for this one thing, it would be worth the purchase; however, it is loaded with information in a condensed package. I advise purchasing the CD version. It takes awhile getting used to navigating (at least it did for me); but, now it is easy to find stuff (and you saved about $300 versus the printed version).
