I tries loosening the pivot nut and hitting it with no luckTwo blocks of hardwood V'd and bolted together to clamp on, or undo the LCA lower pivot nut enough to give it some slack and give it a wack to drive it and the bar back out of the cross member.
I'm working on a 69 road runner that's been sitting out in the west Texas for over 30 years and had to crank up the left side bar 2 complete turns over the right side bar to make the car sit level. Maybe the rear springs are hosed too....?seriously, unless they are fairly new........ if you're going thru the trouble of taking them out (for whatever reason?) put new ones in...... they are fairly inexpensive

This right here.A pry bar on the lower control arm works. Of course the above mentioned advice is needed also.

Keep at it....take a hard mallet and beat the snot out of the bars to help jar them loose then try to back them out. I got lucky on the car I'm working on as the grease was still packed in and looked pretty good for the age but I had to beat on things pretty good. My medium sized dead blow hammer helped imo after beating the snot out of them several times.I got the passenger side out now,but that dang drivers side !!!!!
