Drop him an e-mail, he is an authorized Bassani distributor, and he will give you a price, and answer any other questions you have.
As for the production #, call 1-800-FORD-SVT and you will have to give them your VIN#. They will give you the build # and the date it was built on. Give them your address and info too so they can mail you your certificate too.
Once you have this information,
Taodster's SVT Roundup and drop him an e-mail with your build # and date so he can add you to his growing list of owners and their cars. His site is in the middle of moving/upgrading so that is why you don't see much, but give it time or check out his old site. Sorry, I don't know the link to it. If you have any other questions, feel free to e-mail me.
