Here's one I pulled out from a 1968 full sized many years ago. Its got a big 700 cast into it. Several photos on this old thread. I understand this fits the 9.3" rear end used from 1967-70 for sure, possible back to 1965 but I don't remember the application well enough. Someone else will have to speak up (Joe_p?) John
