issue with AMD Demon floor pan..please help newbie

you're getting there. its looking a lot better. im going to guess that those gaps are tolerances in the amd stampings. i looked at my factory floor, and it is a closed tight fit in those areas. im not sure there is a whole lot you can do about it. i suppose you could try pulling it together with sheet metal screws starting from the center of the hump and working your way out. tack it, then pull the screws out.
