Front impact sensor.

[brokendown]

I have a2002 GMC Sierra 4.8 4x4 180k miles.   The water pump finally said hello and I decided to put in a larger radiator.  All went well with the cutting till I found the front impact sensor below the radiator causes a problem.   The bolts sticking up rub the bottom of the radiator directly in the middle. 

 

Can I cut them down with a dremmel  to give clearance, will that damage the sensor since the bots I understand can not be removed from sensor. 

OR

Can I relocate the sensor forward an inch to get the clearance I need.

 

I would prefer to cut the bolts down but do not want to damage the sensor.
