The 5.0L A/C compressor is different, the A/C lines (hoses) are COMPLETELY different. After doing extensive research on what is involved in removing my 3.8 and installing a 5.0 in my car, I can tell you that they are not the same. You *can* put a 5.0L in there, and connect IT'S hoses to the rest of your setup, but you can NOT use the 5.0L A/C parts on the 3.8L.
