Autohomes pop top removal - pictures?

[volks_womble]

I am intending to take off what is left of my autohomes poptop, and replace it with a Devon one. Whilst petethefeet has very kindly put pictures up of his Devon roof renovations, I wondered if anyone had any pictures of what is beneath the autohomes lower roof - timber framing, edge of hole etc???

Any help much appreciated - forewarned is four armed etc .
Thanks
Mark
