It's unlikely a rear axle shaft from a 1991 Mitsubishi 3000GT VR4 would be a direct fit for a 1997 Mitsubishi 3000GT VR4. While they're both VR4s, there were design changes and potential revisions to the drivetrain over those six years. Differences in axle length, spline count, or even the differential design could prevent compatibility.
Before attempting to use a used part, you must verify part numbers and specifications from a reputable parts supplier or a Mitsubishi parts catalog. Simply assuming compatibility based on model and year is risky and could lead to damage to your vehicle.
