In case anyone else needs this advice, what happens is the bolts just dont line up right due to the fender braces or whatever, what worked for me was to put something (like a short 2x4 piece of wood) between the fender and the tire and pull out while screwing in the bolts, this allowed the bolts to line up properly. Unfortunaltely i stripped one before i realized what what happening but used a tap and die to rethread it. good to go now.
good luck.
