I some how broke the gromet that when you release the brake petal the switch presses into it. Right now the switch goes into a empty hole. Does anyone know what this part is called and maybe a part number before i go running around town. Thanks alot.

I haven't had that happen on my g35 yet, but it did on one of my old hondas. (and I haven't looked under the dash of my g35 for that, but it should be similar...)
If you haven't gone to look for that piece yet, DIY it - on my old honda I wrapped a couple of pennies together with tape, then put that on a strip of duct tape and put that around the brake pedal arm where the hole is.. blocks the hole, gives the switch something to hit against.. give it a shot..
