We are a repair shop for American cars in Germany and are working on a 1958 Buick Limited convertible with a growling noise from the rear end. As we never worked on a car with a torque tube we look for an drawing of the construction somewere in the internet before we start to disassemble. Is there somewhere a manual how to overhaul the rearend ?
Thank you for your help.
