Hi - I know there are a million threads on fender flare swaps, but I haven't see this particular question answered (as far as I can tell.) If I am simply swapping my OEM painted flares for plastic sport flares...not necessarily the liner, do I only need to remove the pop rivets and then re-install the pop rivets with the new flare in place? Or do I need to remove the whole thing and deal with the other two types of snap connectors?

Thanks in advance.
