driving a 1999 cobra with 121,000 on the rear drive train. vehicle has 3,000 on the motor, front end is all tubular and have 20,000. been taking to nasa road raing events and noticed starting to get worse. i recently replaced all the diff. bushings and it seemed to help, but i noticed that the knuckle bushings on both hubs are missing all of the rubber around them. i'm looking for an aftermarket replacement for these but having a hard time finding. the dealer say i can only get the knuckle
