Rear Axle Markings

[BlueSS454]

I finished cleaning up the rear out my 69 today and foind a ton of markings on it.  I was kind of curious what they may indicate.  I'm putting a portfolio of the restoration together and I'd like to document anything I find such as these markings.  There is a 32 on the top and side of the center section, a large yellow stripe on the bottom, a stamping that looks like it is 6-10, an X circled with some sort of number, and something near the fill plug.
