Please forgive my ignorance:
I want to change the brake rotors on my 1980 1/2 ton. It has the stock spindle. One option it has is heavy duty power brakes. It is not a "Big 10" model. How can I tell which size the spindle is? When you purchase new brake rotors, do they come with lugs already pressed in? What about the wheel bearings, seals, etc. -- do those normally come installed in the new rotors? (I assume it's all one unit, rather than a hat/hub setup) or does all that have to be purchased/installed separately?

My experience is with a 1986 so hopefully it is the same. There is a visual difference in the thickness of the rotor and calipers. I think everything else is the same. All the rotors I have bought do come with studs but not bearings or seals. I am sure if I am mistaken it will be pointed out. My $.02

Measure the thickness of the rotor. If you have a micrometer or dial caliper/digital caliper etc.. or even a ruler. The difference is the rotor thickness. Approx 1" for light duty 1.25" for heavy duty
Also it does come with lugs but not wheel bearings or grease seals or grease
