Ron, as Hoop pointed out with his question, it depends on the transmission. If I recall correctly you have a '37 - '39 small-case V8-60 transmission. That would be a bear and would require a good machine shop, but anything is possible. Easy to do if you use either the V8-60 commercial transmission or a normal 85hp transmission (cut out to take the V8-60 starter drive). Or just use a truck transmission that is already open drive. Let Hoop know what you have and he will steer you right. He and I have hashed this out more than a few times. Good luck with the project. Greg
