Help with convertible skid plate.

I have a '04NB convertible that I'm "reconditioning" for my daugters 16th birthday.

I've had to remove the bolts from the skid plate. The bolts were stripped out and had to be removed using tools that basically destroyed the bolt heads. My question is were can I find replacements. I've searched all over even went to the dealership. They keep pulling a part number that comes back some kind of plastic skidplate. Mine is a heavey metal one. I also need screws to attach the skid plate to the side plastic "sound dampeners". There is also some sort of clip that goes on the plastic to allow the screw a purchase point.

It has 6 large bolts that attach under the front bumber and to the supports that come down from the engine compartment. Looks like they may have been a spline type head. It has two larger bolts that attach the rear of the plate to the frame and 8 smaller torx type screws to attach the plastic side panels to the plate.

The part # I have is 1YO-825-235-F
I have found the skid plate in my search, just can't find the screws and bolts.

Any help would be appreciated!
