1969-72 Oldsmobile Cutlass, 442, W-30, W-31 Fan Shroud Lower Mounting Tabs 2pc These tabs were spot welded on the radiator support on cars that came with a fan shroud. When you replace the core support these tabs are often missing. Now the lower shroud does not have to flap in the wind. these are made just like the originals. I have added holes in them so you can fasten them to the core support. You could use the holes for bolts or weld from the center of the hole to the edge and it will look like a factory spot weld. These are the same thickness as the original.
