Removing torsion bars/keys 99 silverado

I got a lift/level kit for my truck and everything is in except the new keys. I cannot get the key separated from the torsion bar. The bolt is out and the tension is off of the bar.

Per instructions the bar is just supposed to slide forward in the lower control arm but I think mine is rusted in. I did not see any other bolts so I guess the tension on the bar is what keeps it in place?

I am very reluctant to heat up the control arm end of the rod as its in a rubber bushing. I have tried an air hammer to push it forward but it didnt budge.

I needed to drive the truck so I put it all back together and with the new bolts cranked all the way in the front is still .75"-1" lower than the back, so I’d like to put the new keys in.

Any ideas?
