997.1 Need part number for insert for bumper cover

2005 C2S Coupe 6MT

I needed to remove the front bumper cover to install a new HomeLink module. A couple of lower bumper cover mounting inserts and screws are sheared off. I'd like to replace them. I'm pretty sure the screw is part number 99907322709 and it's the fastener that takes a 27 Torx. (There are a few smaller fasteners taken out to remove the bumper cover that take a 25 Torx and I believe their part number is 99907323109.)

Does anyone have a part number and supplier for the larger fastener insert that goes in the (lower) frame for a 997.1?

The inserts are square with ears and fit into a square hole in the black frame. Attached is a pic.

If the insert is not available separately, is there an alternate way to secure the front bumper cover?

I found the part number. None of the three dealers in the area had the part so I'll be ordering online.
The part number is 999 591 329 01. Here's a pic. It fits into the square hole in the second pic.
