Richard,
How about sending some pictures of this? I think I understand, but dont want to get into this with a pile of parts that dont work. I still have the original torque tube rear end, with leaf springs, brakes etc. I have never taken a pumpkin apart, but have taken on many other projects with success. Are you saying, that I would litterally remove the "pumpkin" by separating the axels and tubes from the center section, and replacing the center section with another "pumpkin" that has a good gear ratio??? If so, how can I ensure that everything will fit correctly, bolt up, etc, etc?
