Question on identifying a part or VIN number

Hello,
Looking for some help. I have a 2021 Tacoma that came with the factory installed tonneau cover. I never liked it, so I decided to replace it with a Peragon cover. While talking to them about the installation, they said that I would need to order the OEM bed rails. I did so, but when I got them there is large gap showing between the tonneau cover and the bed rail. This is due to the original plastic bed rail having cut outs to allow for the posts and other connections to the Toyota original tonneau cover. What I am looking for is a part number for the bed rail covers that don't have the cutouts for the Toyota tonneau cover. So essentially the plastic cover needs to be completely solid along the entire bed rail. Or alternatively, if someone has a VIN number for a 2016-2022 Tacoma that doesn't have the provision for a Toyota tonneau cover, the Toyota parts guys says that they could use that to order the correct part. Any help would be appreciated. Sorry for the long explanation....

Thanks,
Jim
