does anybody have experience removing the rear end from a 1939 Buick Special 40? We are going to change the gearing to something more highway friendly. So far, we are unable to pull the axles. Something tells me it can't be all that hard, but it may take somebody with more smarts/experience than I to make it seem simple. Please advise!!! Incidently, we have the entire torque tube from a 1953 Buick Special and hope to be able to use the gears or entire diff. from that to give this old girl some legs. Thanks in advance for your assistance.
