The house I purchased has a workshop table with a vise attached to it. The
vise is missing the "do-hickeys" that lock it into place. When you try to
use it, the vise wiggles and turns. How can I find replacement "do-hickeys"
or create a workaround to lock the vise in place?

Is the vice loose on the bench (just the mounting) or (I would assume)
you're talking about a swivel type that won't lock down? A little more
description of what you have/what the problem is might elicit further
aid...
