Some superchargers are designed specifically for certain 3.8L V6 Mustang years, while others require extensive modifications or custom fabrication for installation. You'll need to research superchargers compatible with the *specific year* of your Mustang. Looking at aftermarket parts suppliers specializing in Mustangs (like Roush, Whipple, Vortech, etc.) is your best bet to find compatible kits. These kits often include all the necessary components for a relatively straightforward installation. Trying to adapt a supercharger not designed for that engine is likely to be a difficult, if not impossible, task.
