Help me find the correct rear driver's side seat belt?

[josh2112]

I want to replace my left (driver's side) rear seatbelt as it appears to be a bit frayed. On KiaPartsNow.com, two part numbers are listed: 89810J5500WK and 89810J5500YBR. They appear to be identical in description, except that one seems to weigh 0.1 lbs more (???). I tried using their live chat and asking a question, but their VIN number decoder doesn't handle vehicles manufactured internationally, so they're unable to help with any Stinger basically.

Does anyone know what the difference between these two parts is? Or maybe point me to a better site?

Never mind. All the other dozen or so identical Kia parts websites out there listed only 89810J5500WK so that's what I got.
