I was reading the article about axle swap that Steve wrote. And it states on newer chevy's the backing plate will have to be swapped out for a press on style 13". I've got a 91 k5 and I'm swapping in a 76 14ff. Would I need to swap the backing plate? I don't understand why I would. I'm not sure if he is refering to the axle coming off a newer truck or if the donor axles is going onto a newer truck.... I'm trying to get all my ducks in a row so I can do this swap in a weekend...
