It's not on there
I bought the part in Germany (which explains the German part name), but I'll search around on here and see if I can find it...
Here they are:
F5RZ3078B - Right side - Ford price $159
F5RZ3079B - Left side - Ford price $185
These are for the 4 bolt control arms, which are identical to the ST200 parts.
There are options again on getting parts... For factory Ford parts, type in "ford parts" in the US Google and go to any random dealer. Most people on here use Bill Jenkins at
www.teamfordparts.com or
www.fordpartsonline.com (bit cheaper) or Steve @ Tousley Ford (search on here for his contact info, no online ordering). I'd contact any of these people to make sure they will ship to you. These guys may also be able to translate the FINIS number into the US part numbers (or even your local Ford dealer might be able to...)
Also you can try aftermarket, like
www.rockauto.com which lists the 4 bolt control arms at $85 and $92 each. Choose any 1995-1997 Contour, they're the same part as the ST200. Sometime in 1998 or so they switched all the Contours over to the 2 bolt arms, so make sure you see a picture before ordering! You can try
www.batinc.net as well, but you'll have to call them.
