Are all car and Thunderbird clutch forks the same? Is the angle from the pivot to the throw out bearing and the pivot to the clutch linkage adjustment ball a different angle? In my 1955 Thunderbird the adjustment end seems to be farther forward with the car fork I am trying to install with a clutch which is not a stock one but one more for street and drag racing. The pressure plate is 1/2 inch taller then the Centerforce one I am replacing which moves the adjustment end farther forward.
