I have a Ford Type E transmission (aka Rocket) and bellhousing which is the 4 speed version of the Type 9. (I believe its from a '72 2.0L Pinto.) So the bellhousing to transmission pattern should match the Type 9. The bellhousing to block pattern fits 5 out of 6 holes on the Zetec. The one that is missing is where the starter is on the Focus.
The dowels are too small on the zetec for the bellhousing but that can be fixed easily.
The oil pan on the zetec is in the way of the starter and I plan on getting a different one from a junk yard CVH escort, or just trim up the cast aluminum part to make do.
My problem is trying to figure out which flywheel/clutch/starter combo will fit inside the bellhousing. I haven't tried a focus setup yet since my zetec came from an automatic, but I did mock up a '77 Mustang II's 2.3L setup and the flywheel seemed to deep for the bellhousing.
This is where I'm at for collecting parts for my Locost project.
