1965 Dodge Town Wagon
Should be a 318 Poly if original. Rear gears for a wagon are usually a little lower than the common 2.76. Could be 2.94, 3.23 or 3.55 if ordered with tow package. Make sure the timing chain is in good shape or better yet put in a new double roller, add Trail Beast ignition and drive it across the country! (after checking belts and hoses of course)
