Have an 80 D 150, pulled the slant 6 and A833. Built a 340 for it and found a bell housing for the A833. The pivot on the non engine side is mounted to a bracket bolted to bottom of the cab. Do i need to shorten the z-bar by an inch? If so off one end or out of the middle? On bell housing side does the pivot screw into bell housing or mount on a bracket that bolts to the housing?
