If by disassembly, you mean a diagram of how to take it apart, a service manual would be the best bet. The Helm, Inc are the real ones, factory authorized... expensive as all get out new (
www.helminc.com) but often show up on Ebay cheap.
Alternately, the aftermarket Chilton's and Hayne's manuals are okay, not as good but cheaper. Your local auto parts house or book store will have or can get these.
