issue with AMD Demon floor pan..please help newbie

i took the tension of the torsion bars, it didnt make a differance. i have another floor its a original piece just doesnt have the front pans on it, now when i put that floor in it fits perfect and when i put the front pans i took out back in the fit perfect as well. so i dont think anything moved when i took the floor out. when i lay these piece on top of the amd floor they are the same shape. soo i dont know i feel kind of dumb at the moment :S i can seem to see the problem
