Firstly please don't bother telling me to search, that is how I got to this question in the first place! I have read over the past couple of hours of searching, a couple of references to running Ford TCases or front axles by using some (all) of the doublers/underdrive cases. In none of the instances does anyone respond to the claim. Is this possible? More specifically for my application, would it be at all possible to use a Ford 205 case in a doubler/underdrive application?
