Long story short, I'm looking to surprise a buddy of mine by locating a rear triangle for his vintage downhill bike.

It's a specialized s-works FSR "Dual Slalom" circa 2000, I believe.

My main question is whether or not the rear triangle from the FSR DH team bikes or FSR DH production bikes of the same years would work? Or was the dual slalom rear triangle different in some way?

Any help or information is greatly appreciated! I'm a noob with very little DH knowledge. Thank you in advance.
