Just did a little more digging, it's actually a Fleetside truck. Looks like the 205 was standard in 1970 according to GM heritage center.

And the K series came standard with 3:73 as well.

No RPOs for either gearing, nor transfer case.

It is a Z62 truck with both upper and lower moldings, so if I grab it and keep it, I might bring her back to her glory, a little at a time.
