looking to see what you guys are using, my cub [ 1949] is missing the whole thing, all i have is the hole in the radiator neck, this is a using cub,and i work it , so being a thermosiphon system, it will blow hot antifreeze out sometimes when it gets hot, i wouldnt worry but its doing this is removing the paint on the ajacent hood, the hole in the radiator is directly inline with the sheetmetal of the hood, i also noticed its inline with the rubber gasket on the radiator cap,so im guessing this thing has to be a precise fit , so im looking for ideas or just what the original looked like in case i can fab one up out of copper or something
