Pre'68 Dave: If I am reading you correctly, you can change to an open drive with the parts from a 55-62 1/2 ton and keep the axle housing? Same axles? Same brakes? change the trans rear seal cover and add a drive shaft? I know the final ratio is the same I just did not know the Pinion and carrier would fit. Would this work for all years from 47 to 54 early? Wow! where else would I find that out. Thanks.
