Cletis has it right, the assembly manual is EXTREMELY valuable in both the dissembley and rebuild phases. By your question I have a hunch that you have neither the shop manual or the assembly manual. Buy all the documention you can for your truck. Original printed material is fun, but pricey. Reprints are cheap and contain the same info. Check out Keith Hardy"s project page. He has thousands of hours invested in documentation for free. And if the sprit moves you contribute to the maintainance of the free site. Check the tips page here. Chevrolet offers a restoraation packet that is year specific, and it is free. Also use the search feature there are thousands of pages related to your question. There is a huge amount of information here. And if you ask a pertinant question you will be flooded with info. But asking dumba$$ questions will get you nowhere fast. Did you take pictures of the disassembly? did you do a vocal account of what you dod when you did it? If you didn't it will be a lot harder putting your truck back together even with the docs I mentioned and the help of the people here on the the stovebolt page.
