      I don't see everything, or the pics are cut off in a strange spot.

      is there a way to make the pics smaller not thumbnail size but something smaller then someone can click on it to get the original size.

      i didn't realize the full size when i sent them to you.

      Please note that the table of available ratios has a typo - a 35/35 chain with a 3.05 Final Drive equals a 3.05 Effective (Overall), not 3.42. It's a GM typo that even shows up in my service manual.
