Ive used i Fiat Uno wiper motor and wiper arm, but it was a pig to get to fit right on my mk3 escort because the motor only just cleared the bulkead, and i had to modify the centre hole on my scuttle panel to make it fit!
So, i dont think i'd do it that way again. Apparently the preffered method is to simply modify the origional mechanism by moving the pivot point..... but that made my brain hurt when i tried to figure out the amount that i would have to move it by etc etc
You may well have more room on your mondeo than my escort to accomodate the Uno motor, and its a cheap, lightweight and reliable little unit. If you do decide to try this way (and it wouldnt hurt cos theyre only £5 from the scrappers) make sure you get one with an alloy thread on the main retaining nut- the very early ones ('85-'86) had a plastic thread that lasts seconds before you strip the thread.
I'll post pics of my conversion soon in my project thread ( 'project nk3 escort- bruiser to cruiser).
Lotsa luck!
