So I was changing the cabin air filters, as one does, and I got the little torx screw out fine, and the filters changed, but when I tried to put the torx screw back in, it fell somewhere into the deep interior of the car, never to be seen again. Currently I have the cover taped back on, but don't think that's a good long term solution. Does anyone know what size that screw is, so I can get a replacement at Home Depot or wherever?
