I just got back from dropping the car off for the frame rail repairs. I brought the rear end back with me, along with the springs to be de-arched.
Spent an hour carefully cleaning the rear differential and found some paint marks. Rather interesting in that there is an orange "G" or maybe a "6" or a "9" depending on which way it was intended to be looked at. The G/6/9 is on both the top and the bottom of the center section. Also, some green paint at the bottom edge of the center section (just like on my 72 T/A, which had a giant orange "E" on the bottom and nothing on the top). The rear is a 3.42 posi, just like my old T/A (and built around a week after it in late December 1971).
And the yellow paint on the yoke nut.
