Depends what you mean by "Swivels" From memory the swivels housing (the big chrome dome bit)(539741) is the same but the arms, top & bottom bearings and other ancillary & internal bits can differ.
check up part numbers on paddocks . but i think yule find they are the same. at some point they changed the arms to facics... fasillytate moving the track rod from below to above the axle, or was it friom above to below
