Drilling holes in panels!

[Jeff210R]

Not having built my 7 I'm not that familiar with what's under the skin. I assume all the ally panels are double skinned but am always cautious about drilling holes. Specifically I want to fit a fire extinguisher in the passenger footwell on the N/S. Is it safe to put a couple of self-tappers into the panel at the side or are there any areas to avoid?!

I bolted mine to the floor so I could reach it from the drivers seat. Big washers under the floor.

Two comments - I think self tappers may pull out / work loose as the extinguishers are quite heavy. Secondly, there are chassis diagonals inside the skin which you dont want to hit. Try and find a picture of a bare chassis so you can see where they are. 
 

Oh and the side is likely to have honeycomb ally panels inbetween the outer and inner skin.

How about using velcro to attach the extinguisher? I've found that very successful.

I lashed mine to the `heel bar` cross tube, on the floor in front of the passenger seat, using large tywraps....no problems and just a snip to remove the whole unit

Whatever you do, make sure it is very, very secure.  An extinguisher coming free in an accident could kill you.  I would not rely on self tappers.  Mine is bolted to the passenger floor with some big washers underneath to prevent them pulling through.
