how to find part number for slide-out tray cover that has cigarette lighter

I have a 2003 Buick Century. The cigarette lighter is located within this tray as part of the dashboard at the bottom (below the radio). This tray pulls out and it has this stiff piece of plastic at the front that functions as a cover. The plastic cover has weakened for me and it broke off. I’m trying to find a replacement and on the back of the cover it says the following:

VT 2425
10254271
Retainer - 1/P Ashtray Door
ABS + PC 002

I’ve been unsuccessful at googling and searching car part websites for this part. I was hoping someone could guide me a bit.

Thanks,
