Broken Shifter Bracket?

I have a 1993 NV3500 that I am rebuilding but it has a broken bracket under the shift tower in the shifter rail. I have searched online for this bracket and have only come up with 2 posts in forums in which they show this same broken bracket. My question is can it be replaced? If so, where? I have only seen one parts diagram online (Ken L posted it in a previous thread) that shows this bracket but no parts listing with it. 2nd question is do I need this bracket if I get a new shifter that has centering springs built into them. I suspect this bracket is for the centering. I've enclosed pics of my issue and the parts diagram as well. I believe it is part #11.
