I tried the adapter bushings from Mustang Steve to adapt early tie rods to 73 and up spindles and it looks like it is going to work. Might have to grind off a little on spindle arm but since it is thicker than original arm, will not be a problem. I will post info after I get the vehicle running. This will allow the use of 73 spindles (this is what I am using on my 71) or 74 and up spindles.
