My on-line searches indicate it is out out of a truck. It definitely is not a Chevelle 12 bolt.

Thanks, Bruce. I kinda thought thats what it might have been from. A buddy of mine is restoring a 70 Camaro which is a 10 bolt. He's looking for a 12 bolt. He asked me to run the numbers. None of my books or my online searches came up with that casting. What site did you find it on??? I'm always looking to bookmark good sources.

I found threads on several truck websites by doing a search on the number. Here is one that I found. http://www.myoldtruck.com/vboard/showthread.php?p=1985
