Pot metal HURST shift levers???

I recently had a problem with a bolt on type HURST shifter that I think is an original 64/5 type.

The reverse lever on the shifter mech. was slightly bent out so I took an adjustable wrench and attempted to bend slightly back into the correct position, but instead the whole tab busted off. It broke off easy which makes me think this isn't good steel.

The part exposed from the break looks porous and not nice.

Is this weldable?? is the broken part available as a single part or is the entire mech. now junk??? why did it break so easy....that's not good

what is a good repair idea, because I need this for my valiant that I am currently assembling :(
