doctorwayne's Get off yer duff Challenge (Part II)

[MasonJar]

Hi Wayne,

Could you provide some inside pics of gondolas where you have replaced moulded-on grab irons with wire? I'm having trouble visualizing how to drill - only part way, necessitating very short legs on the grab iron, or all the way through which would then require clean-up or treatment for the inside of the wall.

Thanks!

Andrew
