For a budget guy can't beat a 14 bolt.the old sterling was a
Sweet axle and came w 513 gears.can weld to it and lots of ground clearance. Only thing I have never broke and is still original is my 14 bolt.cheap cheap beef! Weld it and do a disk break kit and you have a bombproof axle for a few hundred bucks. Make sure and weld the tubes on all 14 bolts though.they will spin the tube if you don't.
