got my powerflex dogbone bushes from k-tec 2day, fitted it today also, had fun trying to get the old bushes out, what a nightmare, the vibration is definitely noticeable on idle but the gearchange feels better whether or not thats down to me changing the gearbox oil also. hopefully the vibrations will die down. i got 2 washers with the kit and i put them on the smaller end of the dogbone mount, can anyone confirm this is correct.
