Donor for simplicity...

[scotty g]

It does help but its not quite as simple as with a pinto because the zetec uses a cast ally sump that difficult to weld, i know a fairly local chap thats a wiz at it and pretty cheap too, i cut it down myself and just got him to do the hot bits.
Another option is to use a Sierra CVH sump as the bolt patterns line up.
cheers.
