So now your ready to drill the holes that Brule showed in his post, see 1st picture from Brule's post, you need to drill where the red circles are and the white circles are existing holes.
You will need to remove the inner guard trim to see where the holes go, see pics for info
Now for the warning, don't be an FWIT like me and damage your steering column by being aggressive with the drill just to put a hole in the heat shield, see picture for which hole I'm talking about
The risk of doing this with the other holes is lower but still there, see picture of my steering column
I'm now waiting for my replacement to arrive
Note its approx $400 plus postage for a new one, I managed to get a 2nd hand one from the UK for $80 inc postage (Part number 32306781591)
