1970, Dearborn, October 6th 1969 build date. 9", 31 spline axles, factory 3.91 traction lok.
Ok, my axle housing is all cleaned up, repainted, and ready for me to put marks back on... and I'm trying to figure out this orange number so I can attempt to recreate it somewhat accurately. I THINK it looks like a 19 with a small line under it, but does that make sense? I've not seen many other examples to compare it to. I also found a X9 inside the center section, and I'm wondering if that "19" could actually be "X9" as well.
