torsion bar problem!! wont line up

so i replaced the cross memeber in my 67 valinant becasue the passanger side had tore apart where the torsion bar goes through at. we pulled the doner cross member from a 72 and i just set it in there to test fit and i wanted to slide the torsion bars in to make sure everythings good but the hex is about a 1/8 of a turn off so it wont slide into the control arm could my torsion bars just be completly screwed or is there somethin im missing?and yes the tension is completley off of them. im lost on what i should do i dont wanna buy new ones if i dont need them.

thanks, john
