hood moldings help!

so im trying to get hood trim for my 70 dart. the chrime peices that go on the end of the hood and the fender extensions over the headlights (i think some call those smaller peices "eye brow moldings"?) anyway, my car was a base model /6 from the factory and never came with these chome pieces. its something i want to add. how in the heck do they mount? i dont see any holes at all in my fender ext.'s and im not sure the little holes in my hood are for trim.

can someone here help explain? have pics? am i gonna need to drill holes or what?!
