I have '62, a '63, and maybe a '64 diff here in Vermont, but unfortunately, they are all in vehicles, and maybe not the ratio you''re looking for. You can have one for free, and can even take the whole car, to dis-asemble it at home. All are LHD autoboxes. Also have a '60 P5 LHD w/4spd & OD that would like to find a new home. Very reasonably priced. j
