v8 k frame

Im in the process of swapping my slant 6 k frame to a small block k frame on my 69 dart. The trouble im having is getting the passenger side torsion bar put in. I got the drivers side bar in easy, but on the passenger side I have to undo the upper ball joint to get torsion bar lined up with lower control arm then when i put bar thru it doesn't go on so easy. Is it ok when there is no movement in lower control arm when torsion bar is on. My drivers side had a nice wiggle to it. Thanks dustin
