A-body LCA 67-72 vs 73-76 differences?

So why I want to weld on my own is because the tabs are at the end of the arm. Most aftermarket bars use that bolt in "L" bracket at the shock bolt which is inboard of the factory location. I want to use the factory location because that LCA sway bar mount location is like a cheater bar. The further out you apply the force, the more leverage you have.
The problem with that, is the stock location for a '73-6 sway bar tab is even more inboard than all the other years. It's almost in the center by the limit bumper.
