There is another issue.. the tie rods. They are super angry going in from the top. No other way to do it since the tapper of the center link.. so there IS a difference between lower ball joint/ steering arms from 72 on up. the arm must raise up and correct this issue. You COULD drill out the center link and use a rod end style from the bottom but it will mess up bumpsteer pretty bad the geometry is very pissed off leaving it under.
