Did you say you did or didn't get the Molle bag straps through the vents ? I think you did but if not you can take the vent door off with one of those trim pieces and it pops off and then you can trim the back piece on the vent or do like us and didn't have to. WE just a big screw driver and pushed them through. it came out niceI couldn't get the MOLLE bags snaps through the louvres... picked up some $ store velcro straps and we're good to go. Large one has a first aid kit, one for my other sweet Amazon find - the survival kit, the other for miscellaneous.
