glovebox woes

Hi

I took the glovebox out to try and find out where a leak is coming from but I've gone and lost one of the screws. To remove the glovebox 5 screws needed to be removed, 2 outside and 3 inside, its one of the 2 outside I've lost. I've looked on VAGcat but under the section of dashboard/dashboard fittings the id number i think I need is 52 but the list only goes up to 46. Does anyone know what the part number should be?
