These aren't interchangeable with wheel caps.
In the photo you posted last the stock wheel center caps have been painted black. remove yours scuff, with a scotchbrite pad rattlecan with black paint. let dry, put back on
My bad i should have stated in the photo that shows the complete 4runner the factory center caps have been painted blackThose weren't painted center caps. I'd like to do what OP wants as well, but I don't think they will fit on the rear. I think I'm going to just paint the exposed rear hub after brushing that rust off.
