If you've been around 240s long enough, then there isn't much you should have to ask or inquire about. The problem is nowadays everybody expects everything to be handed to them on a silver platter, rather than searching for the answers themselves. An FSM along with searching TR/FreshAlloy/Zilvia is about all you need to answer any question about the S chassis (since about 95% of the threads in the section here cover S13/S14). Hell, the FSM tells you how to perform troubleshooting if a part is suspect.
