Just started to install a Westin Bull Bar in a 2011 SR5...can't get the 3 factory bumper mount bolts off...sprayed the bolts with penetrating oil...have a breaker bar on the socket 14mm (so its a small bolt)...I feel if I apply any more pressure I'll break the head of the bolt off! Any ideas?? Could or should I apply heat to the bolt...use an impact ratchet on the bolt?? I sure don't want to bust it off..need to remove three each side...thanks Dan
