This is the exact same vehicle as the Subaru Justy of those years of manufacture, except for minor trim differences. I would, therefore, begin with a visit to a Subaru dealership. If refused cooperation, I would then visit other dealerships.
You could also get a bushing made, by having a bronze tube machined to fit or maybe even have one printed from a 3-d printer, if the original was plastic, as a last resort
