Thanks to @Tall Steve for sharing his VIN with me. I went to my local Chevy dealer who was nice enough to look up the part numbers for the red seat belts. These part numbers are for the complete assembly with the tensioner as they don't appear to just sell the belts without the tensioner.
I'm sharing them below but none of the online parts sites seem to even list the front belt part numbers. My dealer said there was zero availability on any except the passenger front belt.
Front right: 86771460 - $275 list
Front left: 86771467 - $275 list
Rear left: 84815184 - $105 list
Rear right: 84815180 - $105 list
