this isnt really technical but im having one heck of a time getting my fender flares off. i got that 8" peice off the front on both sides and well... it left 2 big holes in the side. RIP!! but with the other 4 i want to keep and re-use. they look simple, but like i said i just cant do it! the plastic "nuts" keep spinning and when i tried to hold them with pliers they would brake! and ideas or advice would be greatly appretiated
