Again from recollection of prior discussion, the bracket itself wasn't the issue, but some problem w/tank welds. I could never figure out why that wasn't repairable. If you can weld pieces together, then why not a weld repair over weak welds? I can do that w/steel, but don't know that much about welding aluminium.
I think when the redesign of the radiator came about, they took a look at the whole design and went hella-strong throughout, thereby buttressing the mounts and adding bushings so as not to have to revisit replacements in the future. This was a lawsuit tween WRV & Radiator Specialties or at least threat of one, and RS coughed up 100 or so replacement radiators for WRV to dole out as problems arose.
IIWM and I had the OEM radiator, I'd do the bushings and watch my coolant level.
FYI- Mexican friend suggested a couple cups of ground black pepper in the coolant. Apparently that's a local favorite and know to stop leaks in the right circumstances. Or if you want to spice it up a little more, try cayenne.
