Carpet fitting question in Daimler V8

I am fitting some carpet which I have cut from patterns of an original set. I have trimmed and fitted the rocker panel piece on drivers side including getting around the handbrake. Then there is a large oblong section which covers the under seat frame across from the tunnel. In addition there is a “filler” piece which covers the joins inside the door sill under the handbrake lever. I cannot fathom out which piece goes on top and which goes underneath as non of it seems to be neat enough. I am pretty sure there is an overlap joint to the rear of this small filler piece but where does it go on the forward edge? Non of these pieces are with a bound edge which means it will never look nice. Can some kind soul take a photo of this area to jog my memory please?
