Air box quest

[Bossshelby]

Hi all I have an 85 Honda spree with an 87 elite 50 engine. The problem is th 87 air box is too big for the stock spree panels. I have tried heating and stretching the panels and even cutting them with no success. The elite engine has stock carb with a 90 jet and a lot of intake and exhaust porting and a custom elite exhaust pipe I made. My question is if there is any airbox that would work in replacement of the stock elite one.
