67 383 4spd originality

the 67 four speed should not have the number pad on the side so that is a good sign ...you know its a pre-68 trans .....but very important is to check if its 30 spline on the output shaft meaning it should take the larger 727 type slip yoke if it is an original trans that was behind a Big block......

also big block engines specific to A-bodies should hade the motor mount tabs farther foward ....you should be able to see on the driver side visually if the mounting tabs are farther foward than a regular chrysler 383.
