    307564 - 1952-1954

    398525 - 1953-54 Jet



    Both "P" type (Bolted Cover)



    Don't have a rear axle ratio list to hand, so don't know what the other one is.

    Les, as far as I can ascertain, the only diffy that had 11/50 ratio was the '52 onwards Dana (P type). Used as standard on overdrive equipped cars. The same overall ratio was fitted to the earlier models, but they were 9/41. That 18519 number doesn't ring any bells in my library! Hope this helps. Best wishes,

    Geoff.

    45/11 = 4.08 to 1, 41/10 = 4.10 to 1, 50/11 = 4.54 or 4.55 to 1.
