My recolectioin from when my grill was removed, The surround is mounted with multiple plastic tabs with screw inserts to open them up. The clips allow for a snug fit. I believe you should be O.K, just slightly more loose at the bottom. However, it should be fine. You could always JB-weld/plastic weld some new tabs on, or zip tie worst case scenario. I say buy cheap and go for it.
