I got four police blue SFB. Do the rear SFB have the four small screws embedded like the fronts? I read where you have to cut off the screws to fit the police bushing in the rear? Also why does the recall bolt/washer have a shoulder on it near the center? It makes the big washer "stand-off" the rubber bushing! Will that shoulder slide into the new bushing? When they did my recall, they just left the old washer on and the new bolt/washer shoulder rests on the old washer. So there's a gap between the new washer and the old one!
