I'm sure the single will work but not as engineered by GM
I was a bit concerned when I received the part, the overall difference between the 2. I checked the site I purchased, overall did a google. From what I could tell, the new part is all that is available. As you stated, my C20 will not do the work it once did, and should be fine.
