Use a torque strap or chain. Use 6 to 8 inchs or what ever length is needed . Run a 3/8 bolt into the front of the head on the side that raise through the link on the end and attach the other end to the frame, so there is limited slack. When normal movement is happening no change or vibration added. When it is tugging on or trying to tear the mount it should hit the limit of the chain and stop movement. Steel rope or cable also works great and you can get fancy ends and fastners to build it (located in same section of the store). Use at least 3/16 diameter, and its also available with plastic sleeve to reduce wiskers that cut you.
