Fit all metal edge surrounds ,had a little problem with the edge strips not having enough width to make a nice even clearance with the boot cowl.I obtained some more metal and remade new plates to obtain a nice even gap....well worth the effort.the lower horizontal strip was joggled at both ends to fit nicely over the fwd and rear strips.All strips removed and deburred,and the three items rivetted together at the joggle junction with -3 solid rivets.Reassembled doors and trial fit to airframe.
