Roland Jaeckel bought most of the factory's inventory, so you will have better luck contacting him in Germany than in contacting the factory.
Years ago, the factory had someone dedicated to answering e-mails and the phone (Claudia Lodi) but she is long gone, and it is quite difficult (impossible?) to get ahold of Santiago, even if you have money to spend!
For DeTomaso parts, the cheapest is probably to contact Roland. For Ford parts, it is cheapest to source them from the US.
With the Euro-Dollar, even DeTomaso parts are sometimes cheaper in the US, unless they are exceptionally heavy.
