slop in lower control arm torsion socket.

My car's front end was rebuilt 10 years ago with polyurethane bushings. We noticed the alignment kept changing we also noticed when we take it out to nail the car it would not return to static ride heights it would sit there in the yard and look like a gasser for a couple of days. I started breaking down the lower control arms today. On the passenger side I got the arm out of the tent out by hand and then pops the bushing out by hand. I was able to send sing in an in and out at will, although the bushing stay when I pulled out the pants but then I can pull the bushing right out. I noticed play in the torsion bar socket. How much is to much? I figured once you load the torsion bar in the body that's going to take a lot of that out of there. I grabbed one pair though stiffening plates I was going to have a buddy of mine check on the bottom of each side when I have impressed the new pins and rubber bushings for proforged in. He doesn't know **** about our cars. He thinks all motor oil thru th push rods I had to prove him wrong on that years ago. We had $100 bet on it but I'm not an *** so I didn't take his money. Is there anything I need to look out for when I have them well those plates along the bottom of these things? And if I have him weld them up, can I add new adjusters for the torsion bars down the road? Or will the grooves in the threaded part of the adjuster not line up? I just hope this cures my situation. THANKS Y'ALL!
