1994 Pontiac Bonneville rusted bolts

I am trying to replace the front struts on my 94 Bonne. I purchased Monroe Quick-Struts so I wouldn't have to mess with a coil spring compressor. The problem: the struts I am replacing are the originals, and the bolts that connect the lower strut to the steering knuckle are rusted tight. I spent 10 hours just removing the nuts, and have spent nearly the same amount of time on the bolts. I've tried tapping, hammering and pounding the *&%$ out of them; I've sprayed 2 cans of Liquid Wrench; heated them with a propane torch; and, I've ruined 2 ratchets trying to torque them to break the rust. I am open to any suggestions -
