There a relatively square jacking plate on the bottom of the engine/tranny crossmember. This piece in question is sandwiched between that jacking plate and the bottom of the crossmember. Its right below the front swaybar and steering rack. I cant really see how its dampening vibration as the jacking plate is solid steel and spanning the same exact space but I dont know.
i know the one you're talking about. the rubber square under the frontmost jack plate. its there to dampen vibration, i thought it wouldnt do much until i took mine out, it does make a noticable difference.
i read about it on a page, i dont remember for what, i think it was an install how to for katboy shifter bushings, or maybe a primative racing skid plate. if you use the car for comfy riding and such, i'd leave it in. taking it out doesnt make the ride any different, but it keeps something from vibrating that was annoying to listen to (at least in my case)
