Sorry the site did'nt live up to your expectations. In the immortal words of Elwood Blues, "What da ya want for nuthin', a rubber biscuit?"You were interested in a piece of kit over a decade old.What did you expect, a "Carlini Torque Arm - Ten Years After" article?The article the site brought up for you is fairly comprehensive. What else is there to know? The CTA was used on horsed-up Dynas to help prevent cracking the inner primary cover. And, I seem to remember the chrome wasn't so good.IIRC, Harley came out with their own version after denying there was any need for it for a year or two.
