Stop typing with your teeth and post a picture. This is WAY too vague a question for anyone knowledgeable to even bother trying to answer.

Very often, Dyno's used CR-MO for the main triangle only and had cheaper stock parts, where GT's were often 100% Cr-MO with better parts. That's it, in a nutshell.
