Just to let you know, and I'm not trying to be a smart arse. The 7.5 axles are the exact same as well as the brakes...only the ring gear and pinion and housing are different..Just wondering do you have a rear axle already? are you looking just for the axles or the whole assembly?? if your just looking for the axles you can use the ones from a 7.5 along with the brake assemblies..
