Yep. When I replaced the radiator on my E36 it was a real pain to pull the fan shroud and fan, so I cut the shroud horizontally across the middle and pop-riveted a tab on each side while it was out of the car. Later, when I replaced the water pump and tensioner pulley (and deleted the fan), it was a breeze to pull and replace the upper half of the shroud, with the tabs guiding it into place. Paint the pop rivets black so purists won't faint.
