I have not had any problems yet with my single ear diff mount but know a few that have. i have seen the diff rip the boot floor out on one car and pull the hanger off another. Prevention is better than cure so i thought i would fit the twin ear cover to the diff i am fitting to the e30 that i am building and it is much easier to do now without anything in the car. i took pictures along the way and can be seen here if anyone is interested.
