I've tracked down a set of front/ rear chevy 14 bolt axles locally for $1000, Dana 60's but I don't really know a lot about axles. They're 4.11. My 715 has a 350 in it now and the stock transfer case/ drive shafts. Will I have to shorten/ lengthen the driveshafts to swap or otherwise mod? I want to add a 4BT eventually . I know the CUCV has 4.56 gears. What would be best for hilly backwoods driving on clay roads? Should I just keep looking for a surplus CUCV?
