Rear differential/housing dimensions, sizes and exchange (?)

Can someone direct me to a web site that contains the overall dimensions for rear ends? I had a web site saved and when the wormage started sneaking around I lost most of that stuff. Dammit. Something with overall widths, hub to hub, etc. Anyone have anything?
