GM 2724966 seal on backorder?

Looking at GM's "top 10 SPAC cases" list, I noticed #6 is part # 2724966 seal with 3,094 backorder lines.
Really?
An f*ing o-ring? Moreover, an A/C o-ring in July with no idea when they will have stock?
I can maybe see turbos and cat converters but an o-ring that's been around for years? Really?
Ok, I feel better now.
