bolts on tail lights, help! stuck! Options

[JoKeRkId613]

okay, i installed my curren tails long ago. but i keep burning out the fuses for the turn signals and the red lights when the low beams are on. i keep having to replace them over and over and over. anyway, i think plyr was the one that told me i probably pinched some wires or whatnot. so i try to take off the tails but.,.. i tightened the bolts too much when i first put on the tails and they wont come off! the bolts are stuck. i think i messed up the thread. is there any way to take these bolts off or do i have to saw them off or something?
