Yep, that's where I got my info too. They also show this casting number for early '70 with L78. Seems odd that it was cast in mid '68 for LATE '69, early '70 applications. There is a note near the top of that page that states there is a documented axle cast date of December '68. This one is 6 months earlier than that.
Bummer they didn't do partial vin stamp on axles too. Be interesting to know if it sat around for 9-12 months or was, actually, installed in an early '69 with L78...
