no sweat, i was just messing with ya .I dont know really the right answer since the trucks ive always had i kept 6 lug and most guys running 5 lug have gone disk brakes but i did a 5 lug drum search and seems like guys use the 71-75 5 lug drum axles or have their drums redrilled. i might be wrong but here's one of the threads i found, some of the other guys should know for sure.
