Series 3 legshield question

Evening all,
Just dropped bodywork off at painters for a respray and remembered that tip about the lip on the rear of the legshields (under the bridge piece). They're new legshields so the lip is still at 90 degrees.
Question is: is it just the top needs folding under, or all three sides? I read if you don't do it there's a possibility it digs into the wiring.
Thanks
Marki
