Any reason not to JB Weld the radiator bracket?

Easy to resolder:

Drain coolant down to below the top tank. Clean both mating surfaces well. Warm the 2 parts and brush on soldering flux to clean more.

You can tin the 2 parts with a little solder, wipe off excess with a shop wrag while still molten.

Then have a friend or associate push the strap to the radiator, warm it up with the torch till the solder starts to melt and add in more solder as needed to make a strong bond between the parts. Can wipe quick with a shop wrag while still molten to make a neat job out of it.

Let cool, and good to go.

Paint satin black if you like, but wipe with reducer first to kill the greasy residue from the flux so the paint will stick.
