OK Kevin I'll take a stab at this one. Your kick pannels were cardboard. You can make new ones out of metal or get the cardboard ones from any of the vendors.

Now as for the curved piece of metal on the fire wall I'm not sure, but you might be looking at the cover for the drain for the cowel vent. If thats the case there should be a metal tube on the inside of the fire wall and one from the drain hole in the grove of the cowel vent. These two metal pipes are connected together with a short piece of hose.

Hope this helps.
