Where can I find that part?
As most of us with SHOs have found, SHO specific Ford parts are often not stocked at the local dealers, resulting in long waits while your car lies in some partial state of disassembly waiting for your dealer to locate the part it doesn't have. This can be even more frustrating when you're doing the repair work yourself and intend to use OEM parts, but can't locate the specific one. That's if the part is still obtainable, which is not often these days.
Thankfully, the internet has some solutions for this problem.
The first thing is to find the part number for your part: https://www.dropbox.com/s/iz0c85idjoi3pa7/Parts.xlsx?dl=0 No need to create a Dropbox account. Also contains info on a few aftermarket parts (pricing info out of date).
Next, check Dealer Inventory at https://www.partsvoice.com/ Enter Part numbers without the dashes and convert F0 (zero) into FO 'O'
For no longer produced parts: http://www.greensalescompany.com If they have the part you are looking for, they will be listed in the PartsVoice results.
For USED PARTS, Another good parts locator is http://www.copartfinder.com/. This site searches a massive database of "recycled" car parts for items from a wrecked car of the same make, model, and years you specify. You can even restrict by location by entering ZIP codes.
Or you can look for parts yourself by going to https://row52.com/. Search for vehicles, enter the desired date range, make, model (Taurus), your zip code and search range. This will return all the Tauruses within your area. Once the results come back, do the following to reduce the list to just SHOs. Click on the VIN search button top left of the page, enter 'P54' into boxes 5, 6 and 7 of the VIN, and SEARCH. Parts prices will be a lot cheaper if you pull the part yourself.
For current (mostly aftermarket) parts, https://www.rockauto.com/ sells at a good price. Go to this thread to find a current Rock Auto discount code: www.retailmenot.com/view/rockauto.com. You will have to copy and paste the URL into a new tab: it's considered unallowable spam by Wiki SHO with a direct link. Enter the code into the 'How did you hear about us?' at checkout.
Last but not least is https://shosource.com/. Here you will find a lot of custom parts that are unique to SHO Source as well as other aftermarket parts.
And http://www.shonutperformance.com/, one of the earlier SHO Specific vendors. The go to place for high performance cams, pistons, transmission parts and much more.
