front bed panel, used dash speaker, exhaust shield ?

[sleepertruck72]

I removed this panel from my 72 c-10 longbed w/ wood floor. I dont know the difference of a steel floor panel but from what I have read they are different
Has some surface rust but none all the way through. One of the corner bolt holes is tweeked slightly but will work still. I am asking $25 obo
I found this speaker in the dash. I do not know its working condition. The wires are cut and I dont know how to test ?? $10 obo
I found this shield under the wood floor right where the exhaust pipe was. I am assuming it is a heat shield ? $5. All prices do not include shipping.
