I'm replacing the Fordomatic in my 55 Tbird with a C4 transmission. I know that the C4 and 57 Tbird speedometer cable and driven gear are the same, unlike those used in 55-56. I know there is precious little space to work in, so I will be installing the cable in the C4 transmission before the engine & transmission are installed.  Here's my question: If I use the C4 speedometer cable & driven gear and install them while the engine and transmission are out of the car, will I need to use a cable angle drive as was used in 55-56?
