Isn't a Sport Satellite designated a "P" (premium) vs. a GTX designation of "S" (special). I was looking through a book somewhere and it listed the GTX before the Sport Satellite. Have no clue where or what book that was. I'll have to think about that for a while. How are they listed in the parts books? I'm thinking the GTX is before the Sport Satellite. I could very well be wrong also.
