Looks like it kind of comes up short on both sides, like you said 1/8 on both sides. Also looks like your horns are in the way. Get a final pic with it bolted down and maybe it will look better. I know you have to drill some holes on the top though so you can bolt it down.
They are also used if you have bumper sag... i did to begin with but they worked so well I just eliminated the inner screws. I took some clips from work Ali them in there and used the fasteners to hold it up. Seems to be working lol
