Good progress, impressive. I'm way behind you but trying..... I have the same compressor mount that goes in the plugs in the head but the back mount bolts to the the top two exhuast manifold studs in a "C" shape. Your bracket that extends down to the alternator mout seems a much better solution especially for me since the headers I have don't give me enought room to get the bracket between the studs and the exhaust. Do you or does anyone know where I might find one of those. I'm seriously looking at the classicautoair package shelf unit as there just isn't room under the dash without the cutting involved. Their complete unit with compresssor, hoses, airbox, hardware is right a a grand US and looks like a good quality unit.
The passenger seat is 15 miles an hour faster than the drivers seat.
