The newer metals like Mikes were different and I thik Dave pointed out that you would have to make an off set hub if you want to use it, If the carrier is ok in your newfound diff, just put it in your housing and use your axles. It looks like the sprockets were put on inside out from the pics so it must of come off a narrow? See Orins pic of a proper set of aluminum sprockets on a narrow. Your diff won't have any trouble handling the 300 six. Lots of them around here with V8's, unless you are going to do some heavy freighting.
