OP...check the make of radiator and ET if you can...I really don't think you ought to be sanding down the radiator neck as I'd be concerned that you wouldn't get a good seal afterwards.
Usually with things like this, you'd figure it out 5 mins. after you give up.
This huge woman, like 400 pounds comes up to me and says, "Doug, I would rock your world." I replied, "but I need to breathe." True story!
