A body big block power steering gearbox

The power steering boxes were the same in that vintage, Later years used a larger pitman arm size. K- frame was the same for B engine A bodies and used the same engine mounts (except 440 cars) The 67 K- frame used the cantilevered style idle arm mount, that was the difference, 67 only. 67 Dart/ Barracuda 383 did not have a power steering option availability. The 67 Drivers side exhaust manifold design was the issue that prevented power steering in that year. 68/69 Driver side exhaust manifold for B engine was changed to accommodate power steering. So the 67 driver side manifold is a 1 year only deal.
