GM A/C Compressor

[GovtMule66]

Can someone please tell me if both these GM A/C Compressors are the same or is there something different about them?  My vehicle calls for GM Part # 85656961 but when I enter that particular part number on Rock Auto it brings up 2 separate GM compressors with different part numbers.  On another website I found the information in the 2nd photo that shows GM Part # 85656961 superseded #86798574, #84203715, #23478533, #15-22310 & #15-22293 which makes me believe they are both the same.  Thanks in advance for the help

If the part has superseded numbers, then it's still the same part but with some sort of upgrade over time or it now fits newer applications and they change the part number for everything.

Would you have any concerns ordering one of two a/c compressors I listed from Rock Auto? 

 

Thank you for the help

Not at all, they are GM parts and for sure will be good quality.
