trouble with driverside strut/torsion bar

Trying to put the front strut in a 67 barracuda on the drivers side. it was out of the car when I started but I can't get the tortion bar to slide back. the otherside went back easily but I just can't get this one to break loose in the back.

any suggestions for getting either the torsion bar to move back or the strut in? I've got the hex part of the bar in the back (where it goes through the frame) soaking in aero kroil, but still can't get it to budge.

Thanks,
John
