Snow Blade

My Grandfather handed down to me his Farmall 200 with all the implements. I really need to hook up the snow blade. I have the manual but I did not see where it shows how to hook up. The problem is the arms that come from the sides of the tractor, have a swivel head that is like a house shape with a tail. I am not sure if the tail is to be at the top or bottom. Can Anyone help me get this figured out I would really appreciate it.

If it is a front mount blade, the piece I think you are talking about has the narrow end up.

So the semi pointed end would point tward the hood correct????
