Read end identification

[Matthearse]

I have  10 bolt rear end and am trying to find the year it is off of.  It is 66" hub to hub and has TAAK 013 or 017 stamped on the axle.   The ratio is a little under 3:1.   It looks like the rear end on my 96half ton.  What ratios were available for these?  Anything under a 3.4 but higher than a 2.8?  The dimensions are perfect for my 56 hearse.   Thanks

Sounds like a 2.73 ratio: I had that same ratio in my 83 c10 with a 10 bolt. Could be from that era.
