BACK ON TOPIC... dropping the front driveshaft and installing a 2wd beam does nothing for the added weight, and drivetrain drag, so really wouldnt get enough to make it worth the effort... There is some discussion to be had on front beam style... theres a unit bearing/dummy shaft type, and one that actually has serviceable bearings. My guess would be the serviceable type would get better mpg due to less drag.
