I'll second the recommendation for Cardinal Performance.

Chip is a stand up guy, and went out of his way to make me happy. I got a 41k mile early redtop clip there with everything I need PLUS a spotless new T25 from an automatic SR20DET since the one on the clip didn't quite "whistle right." Seeing it run in front of my eyes sold me.
I don't know if he ships the clips, but I would say if you can drive close to Atlanta, look into Cardinal Performance. The customer service is probably the best I've ever had IN MY LIFE. I was more than pleasantly pleased with my purchase as you can tell.
