My disc axle donor is a 2006 E150. 2004-13 E150s use the same 5-on-5.5" lug pattern as all Broncos & most pre-'97 F150s, which is why I chose this for my "factory" rear disk swap. Unfortunately, the spring & shock mounts are NOT in the same locations; the e-brake cables are very different; and these brakes are too large to fit inside 15" rims. So it's not a bolt-in swap.
