The axle stamped code is on the front of the pass
side tube. I have seen them all along the tube between center section and spring
flange.
There is also a cast date code in the center
section back side in the rib corner. You need the cast date code to
tell what car it is from.

Subject: [Chevelle-List] Where's that
rear axle code?
I'm
trying to figure out if the 12 bolt under my '72 El Camino is the one that
came with the car. I got under it with a wire brush and knocked off a lot of
dirt and grease. My "Catalog of Chevelle, Malibu and El Camino ID Numbers,
1964-1978" says "It is located on the bottom of the left or right axle tube
adjacent to the differential carrier housing." I brushed the
tubes down to a rough state (down to paint but not bare metal). I did not
find the code. So here are my questions:
1)
Is this code stamped in the axle tube? Or is it painted? Or raised
letters?
2)
Does the number go the length of the tube or does it go vertical around the
tube?
3) I
found a casting number in the housing itself, front, driver's side,
3969278NF.
I
truly suspect that this is a wrecking yard replacement. The brake
line fasteners to the housing were loose. There are two rectangular sheet
metal guards (approx. 4" x 6") bolted to the axle tubes near the lower
shock mounts that don't seem to be Chevelle/El Camino related. At least
in the pictures I've seen in magazines and shop manuals, they are not
there.
Any
help is appreciated!
