73 spindles in my 67

Also you will need to mount the spindles so brakes are behind the rotor not out front as they were on the 73 otherwise if you do add a 67-72 swaybar to your 67 k frame the calipers will hit it. Its as easy as swapping spindles from side to side. DrDiff makes the longer hoses needed for 73 up disc brakes used in the rearward position.
