Delayed thanks for everyones input. Been working on lots of projects... I ordered wheel cylinders for a 1958 American ramber and they fit perfect. Its a 7 3/4" gear. Also cleaned up the rear, gasket was leaking badly! And was able to wash it off and take some pictures! Still need a cylinder head for it that isn't cracked!
The 23 on the lower right side of the center housing casting is what identifies the rear end type. Spicer or Dana corporation, depending on what year it was produced. Very likely it came from a Studebaker as they used them in a lot of their lower powered cars. The higher number on the center casting, such as 27, 30, 44 and so on get stronger as the number increases, but the overall width (at least on Stude) remain the same. Studebaker, as well as Rambler used that style of drum for most all of their cars.
