Not to bust a sale - but if you need the radiator because the neck broke off, get some JB Weld, sandpaper, and a short piece of copper pipe to glue to the neck. The repair will probably will outlast the car.

And if you do buy a radiator, get a piece of pipe and JB Weld it in there so the neck won't break off.
