Decoding a 1968 C10 12 bolt rear - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hey All:
I purchased a 12 bolt rear from a local u-pull-it salvage yard that I took from a 1968 C10. The stamping on the axle tube is HR 11 14 K and the mark on the outside of the gear housing is N. Can anyone tell me where I can look to decode these numbers?

thanks,
Joe
