Can someone please

The problem you describe is common. The LCA passes thru a hole in the K member. That hole is a welded tube that has a small weld bead around it. These small welds often fail if the car is driven long with worn out LCA bushings. The welded "tube" loosens up and starts to shift around. Often the hole gets elongated toward the middle. Sudden hard turns can move the hole further toward the outside.
The LCAs will physically interchange from 63-76. They may even fit the early Valiant and Lancer, but I am not sure. The LCAs changes a little over the years though for sway bar attachment and such.
I have modified many K members that have had this type of damage. I use an original as a template and place the tube back in its original position, then weld a large washer around the hole. This gives the area far more strength than it had originally. Be careful to use a washer that does NOT stick out more than the tube. This will help preserve your caster settings.
