I have a 1956 f350 with 514 gears, I would like to change it to 3.5 or 3.73. What is the model number of the rear end so I can order new parts?

Oh Boy 1956 1 ton, I looked back in my old manuals and couldn't find any old numbers for you, but if you are going to go up that much higher you might be better off getting a whole rear end from a wrecking yard with the ratio you want, to change what you have I believe will be costly as you will have to change out the carrier as well as the ring and pinion and all the bearings. Just my 2 cents worth.


Oh sorry a 1956 should be first generation Dana 60.
