Complete 3.54 ratio axle assembly including spring, torque tube, brake backing plates and brake drums for '39-'40 Mercury. Axles and drive shaft turn smoothly. Believed to be an original, unmolested unit - nice shape overall. Purchased it as a complete unit to replace my 1940 1/2 ton truck with 3.78 ratio, but discovered will not bolt up due to torque tube being too long for my application. After checking critical dimensions, it was determined to be for a '39-'40 Mercury passenger car. Call Mike Hurley, 214-908-3301 for more information or email: michaelhurley40@aol.com.
