adding 07 fender vents to older models ?

ive seen a few guys add the 07 fender vents to the older escalades, anyone done this and care to comment on the fit and procedure, ive got an 04 ext that i want to do this too, ive got the vents,just dont want to drill holes without looking into this a little further, thanks

My mom drives one too and i wanted to do this for her, i thought they stuck on with m3 tape
