comes up as "cover (R).lamp" on parts-planet . com for me. sounds right.
That part number is not for the glass lens. That part number is for the plastic shroud attached to the bumper that goes around the foglight.
Unfortunately you will have to buy a new foglight housing...aftermarket suppliers (Depo brand) pricing ~$125 per side. Amazon.com had them the cheapest that I have found.
