Thanks for the information. I do have the additional puck on top with a small notch in it so that it sits flat on the metal cross brace. Still getting a little more vibration than I want though......I am kind of pickie!!
Maybe there is more vibration because back mount is not doing its job??? Not sure...have not looked at it yet.
If noone has pictures, can someone offer me a discount part store part number for the part so that I get the right one? Autozone part # maybe?
