I am not sure about a 1935 but my 1937 and later trucks do not have a rear transmission seal. This is because the u-joint needs lubrication and it gets it from gear oil coming through the rear bearing. The seal and bushing are in the the front of the torque tube. If those fail, you can replace them (assuming you find replacements) or install a quick fix combined bushing and seal, also called an Okie bushing.
