I recently read a thread in which the writer described the benefits and drawbacks of different transmission and rear end combinations to achieve the (apparently) ideal result of ~12.00 for AD trucks. The thread featured the source and ratio of several rears. I think I bookmarked the thread, but did not logically re-name it, so now I can't find it. A google search locates math-based links, but no bolter recommendations. I understand the math, but need the benefit of experience and recommendations. Assistance requested.
