Help installing adjustable control arms

Car is a 03 WRX sedan and I'm trying to install the whiteline kta109 adjustable rear lateral links. My problem is I can't figure out a way to remove the bolts with the rubber caps on them against the fuel tank as they are torqued so tight. I can't seem to get a breaker bar at these so I've called it a night and letting them soak in pb blaster until i get off work tomorrow. Don't really feel comfortable using a torch on this. Any pointers would greatly be appreciated as I am trying to get the car to allpro this week and my other car is a schwinn

 

just let Allpro do it along with an alignment, less stress an effort handling money than a wrench

 

I've done it before on my buddy's wagon. I just can't remember how we got these bolts out
