On my 67 Barracuda with automatic column shift , there is a bracket that has a stud mount with a nut that fits on the transmission , and serves as a pivot point for the bellcrank in the shift linkage . I found that if I took the stud out , and turned it around , mounting the bracket on the Bottom/ or top of the mounting pad on the transmission, it would make the linkage line up when changing between 904 and 727 transmissions . I am not sure if this is what you are talking about , or if you understand what I am saying . I am just trying to help ! Note: my car is smallblock .
