Hub cap question
 

I picked these hub caps up the other day to put on my 3/4 ton. They were in a box wrapped up in newspaper from Feb 24th 1985. Not sure if they were ever used but are in really nice shape. I went out to the barn to slap them on my truck and they are to small!!! I then checked a set of 15" wheels and they fit just fine. Anyone have pics of what wheel these caps came on from factory or pic of truck with these caps on it. I am assuming they are for a standard steel wheel but don't remember anyone ever posting with these caps. Thanks

Those are 69-70 1/2 ton with the chromed hubcap option. On the glovebox label in my truck it says PO3 CHROMED HUBCAPS, not sure if it was the same for a 1/2 ton or not.

Yeah, those are for standard steel wheels, not rallys. There were
also ones painted white, but chrome was an upgrade. My C10 had
the white ones from the factory. Chome ones look nicer.

After 20 years they started falling off all the time, then I lost one,
so I took them all off.

The middle of 1/2 ton caps dimple inwards, 3/4 ton dimple outwards

Not to be too much of a vulture.. but seeings how they don't fit an' all put me in line if you decide to sell em.. ;)
