Thanks for the pictures of the TRF floor pans. I ordered the pans off of Ebay from a Detroit supplier. I now see the big difference, besides price. The TRF pans have much deeper pressings whereas the Detroit ones are shallow, presumably hand pressed. The pressing locations look very similar though. I wish I had seen these earlier as I have installed one side and cannot see ripping it out now!! The sill outriggers may need moved up a little for the hand pressed ones since the pressing for floor attachment isn't so deep. Price was less than half however. Live and learn.
