I just swapped my auto to a 5sp and the rpms are up their on the highway. So i have the rear end gears from the 5sp car. Do i have to change the pinion gear to. If so can i drop the rear end without pulling one of the rear hubs out. Also dosent the autos have a posi and the 5sp has a open diff. Which one would be better to have both wheels spinnin.
