Front lower control arm rear bolt removal (1985 D50 4x4)

Hi everyone, first post here.

I need some help, I'm trying to remove the lower control arm on my D50 (4x4) and it's got the torsion bar springs. I removed the torsion bars but I don't see the other end of the bolt for the bushing. Am I supposed to press it out? I'm trying to use a ball-joint press but with no luck, it doesn't want to budge. I attached a photo of the control arm (the frame is stripped and upside down).

If you haven't done this yet, you need to keep the torsion bar end connected to the control arm. The torsion bar will hold the key bolt in place when loosening the nut.
