10" brakes small bolt pattern fronts

Does anyone know if the 10" brakes with the small bolt pattern are all the same? I have a set of' finned style -- that are small bolt -- will these fit on earlier cars 10"spindles-- I don't have bearings for the hubs-- thanks Lawrence

Based on what I'm reading here, they are not the same. The 1966 Dart V-8 had 10" drums. Can't remember width. The drums did not have radial fins. They had a couple of ridges that ran around the circumference of the drums. Very lightweight.
