My 75 Finally Gets The Attention It Deserves(This Could Take a While)

Also, thanks to two members of this site I now have a replacement for my other damaged rear bumper guard and a replacement for my cracked left hand tail lamp assembly. I haven't picked that last one up yet but expect to do so this week. Thanks to the factory parts catalog and service manuals that arrived recently I've also managed to identify all of the components mounted in the engine bay, and it turns out that once you know the part numbers everything is still out there to be found. Now for my first question. Can anyone identify this rear end? I think I've looked over the site pretty well and cant find any others like it, and none of the rear ends in the chart that's been posted seem to match.
