I went to put in new coner lights on my head lights. I have the the sealed one i guess, the ones were the whole headlight assembly pops out and i can change the indidual bulbs. Any way the long screws that drop down(2 a side), the one broke off on me. Where the washer pushes down on the top of the head light, It broke right there. i tried this "quick steel" its like a pudy u mix, and i tred to glue it together to get out the broken screw but it didnt work. any ideas?
