it can be done if your not too worried about your paint and what not
i use to remove only my top centre mould and grill before to get my lights out
but now i take it off properly with my car,
bar off first
sides moulds
grill then centre
depends if your parinoid
you can get aftermarket moulds, the TYC are a good make of non genuine stuff. just make sure your happy with the product before you get it painted
