MTX,
None of the SVT guys here will know what the hell you are talking about. For some reason most non-SVT Duratecs with MTX use a 2-bolt flange with a spring loaded joint and aforementioned donut, instead of the 3 bolt with flex pipe arrangement.
I don't have the P/N for you, but I can dig through my receipts at home tonight and get it for you.
Bottom line, in Ford-ish speak, you need a donut that is specific to a non-SVT 2.5L manual trans.
