I ordered and now trying to install a 152 DB air horn. Very nice set up and can even be use to inflate tires and inflatable toys. Had to mount the horn facing down in the engine bay because I just didn't want to drill holes in the roof. The air tank and compressor is no mounted right behind the drivers seat in the basement storage compartment, Looks like it belongs and has always been there... Had to order some more airline today but slowly movin along.
