Yes, direct replacement. I believe you also have to replace the rigid foam crash pad/support behind the flexible cover, since that holds the fog lights and may be a slightly different shape.
There are multiple “how to” videos on YouTube.
You can also reference the 1994 factory service manual, page 10-4-4. If you need a manual, free download, thanks to GaryDoug:
