Looking for a NP540 or the gearset. Prefer one with a 1-1/2" input shaft and / or a 6.06:1 1st gear. Don't need the OD version.
This 5-speed trans is typically used in medium duty truck from GM, Ford, and Dodge as well as some others in the 500-600-700 series from around 1959-1978. It has a cast iron case with an aluminum top cover. The data plate is typically on the top passengers side of the case.
The local yards here don't have anything that I can make work again.
