The original 8.2” rear end in my ‘68 GTO looks to have been replaced by an 8.5” one, just judging from the square casting protrusions on the bottom corners.



Trying to figure out what it came out of, but having a hard time finding a casting number through the standard layers of hard crud. I did find the stamping on the front of the passenger tube, looks like: CJ K-044 G. The only casting/date code I could find is not legible, it was on the underside front of the center section, on the passenger section.





From the stamping, any ideas on what this could have come from? Or other areas to check for a casting number? (I’ve scraped off several areas and no luck so far).

Doesn’t look like the mountings were moved or added, but will need to scrape off a bunch more crud to verify that.

It’s not limited slip, and drives rpm-wise like it has 3.36 or 3.42 gears (I’m going to remove the cover soon to change out the oil anyway, so will verify then).
