Well couldn't stop my self so!! For anyone thinking of the same project this is what your aiming for!!!! After doing the rears (one of my threads yesterday) I had to start the fronts, Firstly the inside markings for the exact position of the holes are clearly marked for anyone that's unsure!! (not that clear due to pic taken with phone) but you cant miss them, Remove the bumper as per 'HOW 2' but as i found with the sri it may vary from model to model! (Extra screws or clips + may vary type wise), Also Ive included a pic of them blinkin tough areas to undo again as per the same on the rear bumper(red arrows), Also when the bumper is removed you don't have to undo any wires just lay a cover down and Rest the bumper on the floor, It will help to prise out the clip holding the fog light loom in place on the front slam panel so you can manoeuvre the bumper about, Put a small pilot hole through from the rear outwards as i did, Then use the drill bit provided with the sensor kit (IN PIC) And just drill from the outside - inwards, I done this by just sitting the bumper back in place loosely to make it easier! (as per pic) and then clean the ''small'' lip created by the brill bit so the sensor sits flush with some ''very'' light graded sand paper, dont wory about the size of the hole being to BIG as with the gadgetman kit (as per pic) the sensors have wedge shaped foams around them (wet with water or soapy to EASE them in), Again i would grade this job for any diy type bloke as Fairly Easy, Dont be put off by the pics ''ITS NOT AS BAS AS IT LOOKS'' you will be pleasantly pleased when its done and its not that bad to do, and as you can see Even with the sri (LOW) it can be done on the floor (even as i did in your back garden) ,Iits just the tricky part of ''pulling the bumper sides OUTWARDS thinking there going to 'crack' or 'split' Just a note to help I used a piece of wood (bird cage perch size) to wedge behind the stuck part to help prise it out!.
