I was unable to open the photos but if it has a 4 bolt side cover and the case measures about 22" overall it is likely a 55-57 car or a 55-61 truck. If it has the short tail shaft, about 15" overall, it could be a 58-64 car or a 62-67 truck. They have the same internal parts the main difference is the tail housing. The supplier I buy my transmission parts from calls it a Muncie. Others may disagree.
