We use a lot of Explorer rear ends as they are strong as heck, set up for leaf springs, narrow, disc brakes, and the E-brake cable comes out just like ones on old cars/trucks. Have not had a problem with the "C" clip axles--yet, but if it comes up there are several offering C clip eliminator kits. At 59 inches wide they fit most of the 30's, 40's, and many 50's rides like a glove but if used on AD's or newer trucks a spacer may be needed to give tire to frame/box clearance, especially with bigger tires. Wheels with less back space are available.
