Pot metal HURST shift levers???

It'll weld just fine.
Take it out of the mechanism and grind about 1/8 taper to the ends of both sides of both pieces.
Wire wheel the two pieces clean at least a half inch back from the weld area and fill that groove between the two pieces with a good hot weld that burns in to both and grind it down like it was.
Easy Peasey. (A mig would be simplest if you have one)

I also see where it was already cracked pretty bad before it broke off like others said.
