Just finished mine and I can tell you that you can never take enough pictures as you are disassembling. I messed up by missing out on taking several pics and slowed my progress of putting the car back together. Also, factory service manual is a must. Add all that to a good forum for asking questions is a big help. Another good resource for parts and questions is the son of Chuck Hoffman (Hoffmann Winner Circle) Todd Hoffman. He's into the A Body GTS cars.

PM me and I'll give you his email address.
