catman56 OP member C Joined: Feb 2005 Posts: 127 CT..USA	So I do have a set of LBP axles from a 73-76 7-1/4 rear..The next question is,will they fit in the SBP axled housing I have in my 71 Dart? From the bearing specs from NAPA,it does not seem so..The OD and ID of the bearings are different..

From the bearing specs from NAPA,it does not seem so..The OD and ID of the bearings are different.. also realize you would have to change the brakes , the axle offset of the 2 are more than likely different . I think you answered your own question , if the ID is different, that is the part the axle rides on , then the axle won't fit the bearing in your rear properly . If the OD is different then the bearing that fits the new axle will not fit the housing .

You should be able to do an A body rear for a lot less than that even piecing one together.
