Upper Control Arm Ajduster Bolts

I attempted to change out my upper control arm(Calmini) bushings so I can get the truck aligned and maybe even get rid of the squeaking but one of the adjuster bolts has rusted to the cylinder metal housing inside the bushings. Any ideas on how to get this f*cker out? I've tried hammers, air chisels, ect.....I'm running out of ideas & I'd like to finish this weekend.

If I remember right, Calmini didn't replace the adjuster bolts in their kit right? Can someone with the Calmini UCA's verify that this is still using the stock adjuster bolt so I know where I need to go to get one if I need to destroy it to remove it?

The cam bolts are a dealer only item. You'll have to cut the bolt out by cutting between the bushing and the "A" arm mount.
