Early 69 used a Chrome knob from the factory and mid to late 69 & up used wood grain knob and is verified in the parts book. All these types of shifters no matter what body style or year from 66 to 76 (where used) except E-body can use a wood grain or chrome knob all the buttons have the same threads. Yes the cables do have different lengths or i would not have mentioned it, i have 3 different factory lengths here for this type of shifter The cables need to be different lengths because some of the shifters have different heights and bends requiring different length cables.
