I searched and so far I have not saved a PDF of the original rebuild thread. Here is a link to the thread minus the pics (Thanks Photosucket). I checked the part reference links and they do work so looks like the sources for parts are still good. I haven't given up on finding the saved PDF. http://www.fullsizebronco.com/forum/...w-rebuild.html
Also do an advanced search using Sliding Windows searching thread titles. In one of the threads you will find a link to Steve83 Supermotors pictures of sliding windows. Some details there as well.
need more details. are you looking for the whole slider window and gaskets or just a good set of gaskets?
Also... this is the '78/'79 section and I'm pretty sure those sliders are different but gaskets may or may not be adaptable for the '83 listed in your details.
