Presuming that you just opened the vent then drilled right thru

Yes I opened the vent and carefully drilled through both the vent and pan from the outside inwards. The nice part is that the vent still closes off the new holes when shut which is a must for controlling temps. I initially said the holes were 1/4" but after looking they are larger, I think they are more like 5/16 or 3/8.
