Rare GM Styled wheels? info/value?

[82Diesel]

Looking to know more info on my GM Styled Sport Wheels which was originally a "Frost White" & had a Deeper Dish than >> (Opposite of the Wagon wheels) GM Offered on their pickup trucks...

A good friend of mine Michael Newman on FB (Owner of NOS Square body parts Group) Has told me It took him years to even find a complete set & These even then where very rare, Most where on Sport Trucks but some had them on the 1/2 Ton Pickups like mine, which is a 1982 Chevrolet Silverado K10 with the 6.2L diesel (Red Block) & 700r4/NP-208 Package Both First years for the eng/trans.

I myself have found very little as to Pictures & Info online Except a For-Sale Post of a complete set reconditioned for $800.
Any help to Rarity or Value is Much apprenticed!
