49-56 Passenger cars used aTimken differential. Mercs, Wagons, Sedan deliveries and F-100's used a Dana 44. None of the these have gear sets that will interchange with a 9".

Here are a couple of questions for you guys out there that are familiar with Ford rear ends. I have been told that Ford put a 9" rear end in some 56 station wagons and sedan deliverys. Is this true? Second, is the 9" that was put in cars starting 1957 the same width as the stock rear end in my 56 Victoria? The gear set in my Victoria gave out and we're having no luck finding new gears so we're beginning to explore other options. Thanks
