I used Schumacher mounts,the vibration is noticable. Was gonna switch to rubber on the passenger side and sell the extra, but the stud was too long on the only rubber mount I had that was the right thickness (out of four), got tired of fighting it and put both back in. I have a brand new Schumacher torque strap I bought years ago and never mounted. My car came with a chain on the 340 and it looked like crap.
