IN CASE ANY BODY ELSE IS IN THE SAME SCENARIO AS SAINIside SO AS AN ANSWERED HER IT IS.

Thats good question simple answer NO once the holes are drilled you have limited options of what you can use to replace them as sensors heads are all different sizes (so most times we are required to change the bumper bar cover) Now when i say limited options i mean limited options that are better in sensors head style and reliability we use Ultra Sleek Parking Sensors because of there sleek stylish sensor head and programmable functions they are unbeatable.
Hope this helps someone in this forum

Remember always check your Parking Sensor Quality. We see this all the time customers buy Parking Sensors and have them fitted, and then they realise that they just dont work as they are suppose to, and now you realise you should have spent bit extra and bought Quality Auto Parking Sensors.

Now you have the same issue above to rectify this with Quality Parking Sensors

Hopefully now with this knowledge above you don't get caught out, but if you do ever get stuck in this predicament we can help you.
