I have a rear end under a 61 Lark. I believe it to be a later model rear. It has finned drums. It is a Twin Traction with one of the tags noting: 3.31. That, I know is the ratio. The other tag has in large letters:45B. Can anyone help me with this? Is this the original rear for this car or is this from a later model? The axles are tapered. The backing plates use the later style wheel cylinders. The type with the staggered bolt holes. These are the same one I just replaced on a 63 disc brake car. Perhaps this rear end has later backing plates???
