it should have two d nuts in the front corners. Those attach to the inside bottom of the grille. The other end is attached with two 'L' shaped brackets that you can make yourself. These 'L' shaped brackets mount to side of the front frame and also to the back corners of the pan.
If Mr Rogers sees this post, he has a great picture of the part. After I got the picture from Don, I realized that I had one of the two that Ford produced for 1936. One is a slight curve (to the contour of the bottom of the grille), and the other is a series of creases in the metal to form the contour.
Hope this helps some.
