I have had these for years. They are 15X7. They came from Texas many years ago. I cleaned and painted the fronts but left the backside as I received them, I used stencils so paint is pretty uniform. I have 5 center caps, as pictured, I have a set of 20 stainless steel lugnuts, They are not exactly a perfect match for the Buick lugnuts but look nice. I'm selling all these things pictured together for one price. $1275. If you buy them I will take the wheels to a small business in my town, they will pack and ship them to you at your expence. I have used them before, they have always been reliable and parts have arrived in good condition. You are paying for the packing and shipping. Eack wheel has some curb rash. I touched them up with one of those chrome markers/paint marker many years ago when I painted the centers. All these came from the later model Buicks, from cars in the 1970's or maybe 80's, the big cars like Electra, and are 4.75" bolt pattern, yes I am sure of the bolt pattern. Besides the 5" bolt pattern wheels look different, as you all know. These have about 3 and 7/8 inch back space.
I am sure you are correct, I probably did not measure correctly, or didn't read it correctly, or really don't know what I am doing. I would say answer three is the right one, I don't know what I am doing. These wheels are the 8th design wheels on your chart. I will try to find the part number tomorrow. Thank you for the help, I need all I can get.
