Has anyone else broke or had defective QT motor mounts? I had been hearing popping noise from under(97 D1) and after investigating every other possible culprit(QT's about a year old)(figured never have motor mount issue again right!) the right side mount bolt to motor was gone or sheared off?) popping was the remaining mount moving or flexing I've had so many suspension/drivetrain mods that kind of oblivious to most noises good thing I had checked because was time bomb
