So I have a 2004 Gt 4.6ltr 40th anniversary edition convertible and I was just given a set of 2010 19x8.5Jx50 gt premium style aluminum rims for free. I want to know if they will fit my car, also if I need spacers and what size I should use to get them to fit? Can anyone help me out with this please???

These are the rims i want to use..
