Many Thanks to John and the guys at Marlin Crawler. I just got my Dual ultimate package and what a sweet piece it is. Dual 23 spline cases 2.28, 4.7, dual AA reduction box housings, HD 30 spline ear output, twin sticked, billet rotated adapter. It was awesomely packed also. I cant wait to be able to try it out. Thanks again guys. Jim
