Will these shocks fit guys?

We're looking to get a new set of these OEM autoride shocks for a 2000 gmc yukon with the Z55 autoride suspension package. The current stock ones have 130,000 miles on them, have small developing cracks in the air bags, and one leaks out air when the air compressor pumps them up to level the truck out. It constantly levels with as little as 2 people in the back seat of the truck, and we pull a 2500 lb boat and various other trailers often. I want to replace them before the boat comes out since i know it only got worse from last year, and they were bad then, putting a lot of strain on the air compressor. The guy on ebay says they are off a 2007 denali, and he gives various years that these shocks will fit, but it doesn't say 2000 yukon. I ran the part number and no luck. Anyone have an ideas? Thanks
