DANA 44 Identification help

[hunter1123]

I am trying to determine what year axle I have on my 1970 C10 that was converted to a K10. I know it’s a DANA 44 from looking at the front pinion cover but I cannot find a BOM number anywhere after wire brushing the entire axle the only numbers I could find were on the top right of the pumpkin which is 38335 and has a 1 above it. Bottom right corner of pumpkin says 44-8F and on the long tube side of axle next to the pumpkin there is a lone 2 then a few inches down
3 22 6 7CE is stamped on the axle. If it helps the knuckle has A3R35 stamped as well. Any help is appreciated Thanks guys
