Well, I tried to find you a good link but the webpage has been changed and I can find nothing!
Anyway, for my '99 3.8 (yours will require a different tool), the Ford number is 303-630 (but Ford will not sell you one). The OTC number for the same tool is "6470".
Anyway, try your luck at the SPX/OTC (otctools.com ... I think) website ... it's there somewhere!
