Unless it was in an accident there shouldn't be any alignment issues,there should be 4 bolts with rubber isolators that bolt right in place,even the core support that has 2 bolts for a total of 6 bolts should bolt right in place,
If by chance you find a new windshield you might want to buy a new gasket also,new windshields are usually a bit thiner than an original one and the old gasket won't seal very well
