Hi Poppa,
Summit seems to sell them in 8x16 with Corvette Rallye wheel design. Not sure about you bolt pattern on your Yukon but they shlould tell you if they fit or not. If you google them you might be led to a picture of Silverado with them mounted. Think actually from this forum in the truck section. Wheels seem to come for 100 bucks, (only primed) regardless from whom, trim rings quite cheap but they might charge you a king's ransom for the Chevy centercaps repros ("Chevrolet Division") if you prefer chrome metal, 50 bucks minimum. There are chromed plastic repros available far cheaper, however.
