What year did D60's start in K30's?

Or maybe a better question is what front end should be under a stock '76 K30?
The locking hubs look different than what I have seen before, almost pyramid, or conical shaped.
I haven't been able to look under it yet, just briefly from the side. Any advice on identifying what it is? I tried to google an image for the differences like for a rear, but haven't found anything for fronts.

1977 is the first year GM put a Dana 60 in the front of the trucks. They didn't make a K30 before that.

If it is the original axle in a '76, then it should be a Dana 44.

The ad says '76 and these are the pictures he posted?
Doesn't mean something hasn't been swapped over time I suppose...

That is not the original axle. In '76 GM used internal lockouts. The picture is an external lockout. Looking at the front of the axle, there is a number cast in to the lower right rib of the center section. Post a picture of the steering knuckle.
