early a body torsion bar ?

If you keep the spindle and brakes on the LCA and let it droop disconnected from the UCA, there should be enough weight on the LCA to **** the torsion bar socket down far enough to where the bar will slip right in or tap in from the rear depending on how rusty the sockets are. I don't know the 'proper way' to do it, only what works.
how far do i need to bring the lca down before i try to slide the bar in?
