The single radiator core support bracket which is normally rivetted in the center was welded in place and bolts too short to accommodate the required rubber bushing or any shims were welded in the bolt holes. Additionally, the mounting holes in the crossmember were damaged and plate with holes drilled in it was welded in place over them. The welds look horrible and I have doubts about whether the surface is level.
Your best approach may be to buy a replacement Radiator/fender support:
example and go from there. The mounting holes in the crossmember are frequently cracked. I repaired mine with a doubler on the bottom and welded the cracks and redrilled. Stuff that's welded on can be removed, but you'll need the correct dimensions to get it back together.
I'm a little to far from you to be able to help much.
