One of my step sons is lowering and bagging a 96 Mazda truck and has run into a small problem in the engine compartment. The passenger side front tire hits the exterior heater/ ac box (the one with the blower motor in it) when he lowers the truck. I thought I had remembered seeing some of the older basic "contractor" trucks that didn't have ac and used a different box. Does anyone know where I can get the different heater box, or have any suggestions for me to pass along ?

Thanks
