Question 71 or 72 GP 12 bolt

I picked up a chevy 12 bolt rear out of a 71 or 72 GP a couple years ago. I'm trying to decode it to see what it really might be from but I'm not having any luck.

Axle tube is stamped w T k 038 . Does anyone have an idea what this means ?

I found the info . I was looking chevy numbers on it but it turns out it was the actual rear from the GP so the code was Pontiac

WT is a 12 bolt 3.07:1 ratio, non-posi. K is McKinnon plant (Canada). 038 is the 38th day from the beginning of the year, Feb. 7th and since, in '71 that was a Sunday, I'd say it's a '72.
