After getting my Bullitt up in the air,and removing the rear wheels,getting ready for the gear swap,I notice these two black wedge shape things,one on each side,at the rear of the wheel well openings,behind the tires. Might they be some kind of vibration dampners? Also take a look on the left side,behind rear wheel,and notice that huge black cylinder shaped thing,maybe the fuel pump or vapor cannister,it sure has a heavy gage steel sheild and bracket. Also note the extra bracing going from the rear frame rail to the bumper support. Lot's of places to cut weight for racing only of course! Oh well,back to work!
