So... scrubbed all thru my AZ business and then regular account, only found stupid broken link (show pic of yellow Golden or lab dog), text my parts guy last night; he didn't get back until after midnight, I was afk/ sawing logs.. He said, after 2020, OEM got harder and way more expensive to source (thanks covid/ supply chain), anyhow he ordered multiple units in, and we've had good luck with the Akkon and Spyder units (as far as direct fit, closest to the hard ABS plastic, and clear glass ( not semi- opaque, or vertical striped fogs).. if you still want Delco, CarID website carries them, but you buy each, not in pair, and my parts manager said it'll be about $140+ for both.. here is GM# 15776380 & 15776383..
However, he did send me link of unit that we ordered in Aug. 2021 for about $58. He said this was as close to OEM that he found so far:
