I just installed the SB today. What a difference!!! Not so much at high RPM, but in city traffic, its almost like a new car. I used the install method of removing the vent and panel. It was an impossibly tight squeeze, so i also removed the throttle pedal nut and was able to wiggle enough room without removing the washer. I am a mechanical dunce and it still only took me about 30 minutes.

Thanks to everyone for their help!!!
