LCA's and ball joints - 73 B body

Help me figure this out here?
What Revhendo asked.
You are wanting to tack weld a "press in " ball joint, where a "screw in" ball joint come out of the LCA.
People tack weld a ball joint in a UPPER control arm when the threads are boogered up, but that's when a threaded ball joint came out, and a threaded ball joint went back in, but just wouldn't tighten down.
Your either going to have to buy the proper threaded lower ball joint, and screw that in, tack weld it, and or, replace the LCA's using the proper ball joints.
