Yeah...sleds of that era didn't have radiators. They had heat exchangers, most of which were in/under the tunnel/floorboard area. I don't recall any being fitted up front like you are asking. What are you doing?
Nose cone radiators for the wedge chassis were mostly used by ice racers or hopped up older trail sleds that needed the extra cooling, I sold one about a year ago, to buy one new now is pretty expensive if you can find one, used ones are a hard find, maybe your local radiator shop could make one for you??? there really isn't all that much too them.
