headlight help PLEASE!!!

ok… heres the story… when i bought my teg the guy had been in a wreck and rear ended someone… and had the front somewhat fixed… and i knew about it when i bought the car and it was ok… untill i really looked at what they did… my pass side headlight is pointed lower than my driver side and they didnt reassemble the headlight correctly… all they did was tighten it up with a long screw and this wierd type of bolt that i have never seen before…

ive tried to loosen the bolt and move the headlight but then its all wobbly and moves around too much to drive…

is there any way that i can reposition my headlight? anything will be greatly appreciated…
