where to get archived versions of the viewer ?

im looking to download archived versions of the SL viewer.
from the earliest possible version and up.
i am not concerned about whether it will work or not.
i need some older versions of the dynamic link library files.
i also need to export some functions from the main executable that have been removed in the mandated version and some earlier versions as well.
googling has resulted in no finds.
thanks.

Edit: Scratch my whole post. Re-read your post and saw you just wanted dlls

Use http://wiki.secondlife.com/wiki/Source_downloads

It has precompiled librarys for viewers going back years.

thanks
i thought a good portion of the DLL's used in the source code wasnt re-distributable.
