MAF problems need quick help

Took an MAF off my buddies just bought 94 vert to clean it. Seeing how it was dirty as hell i started cleaning the whole thing and the screen popped off completely. There is a rubber housing around the screen but it looks to big to fit in the hole on the meter and there looks to be no adhesive tht was holding it on. I need to know how to put this screen back on so the MAF can go back on the car.
ANY INFO WOULD BE APPRECIATED
thanks

anyone else ?
