The SVX driveshaft is unique. However, if it is difficult to find another SVX near you, get one from an outback and have it made the proper length. If you find a 95-99 Legacy or Outback, the rear section may work in an SVX if you have the 2 piece driveshaft in your SVX. (most SVXes, especially 92s have a "1 piece" driveshaft that uses a c/v joint in the middle. The "2 piece" bolt together and use u-joints.
Hope this helps.

You may also be able to get someone from here in the states to send you what you need. (Not sure what shipping is like to Mexico)
