69 BARRACUDA FB interior question

I bought my 69 a few weeks ago. The car was completely torn down, sand blasted and epoxy primers. After bring all the parts home and going thru everything, there are a couple things (so far) that I am missing. Behind the folding rear seat in the 'cargo area' I am pretty sure there should be a sub floor that the carpet goes on. Also on each side pretty sure there is a plastic piece that covers each wheel well. Any help on getting me pointed in right direction to get these things would be greatly appreciated.
