Wouldn't bend. But you're right that the threads were making it difficult. It's about a 1/2" piece of steel.
Ultimately, I ended up removing the belt tensioner--which is what the brace is connected to. It wasn't welded either, it just had so much gunk on it that it looked welded.
I just finished up with flushing the radiator. I have to take the whole thing back apart to put the new thermostat in. Unbelievable how difficult it is to replace such a simple part.
I guess this thread can be closed now; unless people want to talk about it.
Thanks for you help.
