One ton axle swap 

You know I can't leave them looking like that.. :)

I sure can! Pretty much just a box with an open filter sealed against the hood under the "mushroom".

@@AttwoodsGarage I have been kicking around an idea similar to that. Thinking about using hood vents and having the vent on that side seal to the air box. Detail on what filter you used and where you sourced the 'mushroom' would be most helpful.
