i seriously doubt you will find a manual tranny in anything other than a work type truck....they are not cool nor popular to the average consumer, i have ridden w/Kornfed in his truck, (6 speed dually/work truck) it seems like he is trying to pick up a quarter of the floor with a baseball bat, i could not imagine driving that on a reg basis...
in fact im now curious as heck to see how many members we have on the forum that even have a manual in the 99-07 body style trucks.
GL on your search.....
