As previously stated, you want motorcraft parts. I bought mine from Geiser Ford on flea-bay for about $120 shipped for both. Great guy to deal with http://myworld.ebay.com/geiserford19...:X:CEM:US:1181
If they don't have it listed just send them a message. I always got a response within a day.
motorcraft syncronizer part number: F8DZ-12A362-AA
Oh, and I used the "no tool" method and it took 20 minutes total. The hardest part was lining everything back up but it has been about 10k miles and I have not had a problem since. A new Sharpie is your friend.
Just remember to take your time. Getting to it can be a pain too. Hope this helps.
EDIT: Looks like you have to copy and paste the first link. For some reason I can never get that one to work correctly.
