so i want to get some LED tailights for my mustang from AM, but i only saw them on the stock set. i didnt see any isntalled with aftermarket tail lights. so if anyone knows can you please comment!? thanks, i am new to this site and i jsut bought my first stang so there are a lot of questions i have. another one is lowering the v6, all the spring kits say they fit gt models. do i need to worry about the engine size? or just pay attention to the year!?
