early a body torsion bar ?

this thing is kicking my butt...i re did both sides,. let the jack down.....no go could not even get the jack out from under the k frame.... ok, heres what i did, i took the bolts out of the uca that let everything fall down with the lca pointed to the floor, slid the bar in, it went in with no issue. used the jack to jack up the lca to get the uca back in place installed the bolts in the uca, put the wheels on let it down no go....this cant be this hard,lol,,,
