The upper radiator supoorts are easy. Take the rubber out of the old ones, then fill them up with silicone rubber. Put a sheet of Glad Wrap or Saran Wrap over the silicone and bolt them down. One week later remove the mounts and pull off the plastic wrap. Trim the excess silicone rubber and you have custom made radiator mounts.
