70 Chalenger filler pieces?

After several years of having my 70 Challenger In pieces and thinking I was selling and than not I am finally at the stage of having it at a shop for body and paint. I thought I had all the pices but the body guy is asking me for the long body to bumper filler piece ( which I have) and the 2 pieces one each side to tie the body to floor as he discribes it. Anybody know what the 2 pices are that he's talking about? Pictures?

Thanks

I would think AMD has it,whatever it is he is trying to describe.
