Cab size???

So heres my situation. I am wanting to swap out my carpet flooring for vinyl flooring. I have found a great price at L M C truck parts. BUT heres the issue they only sell the moulded flooring for 09 2500 quad cab. Is the cab the same size as a 2010 1500 quad cab?? i assume quad cab signifies the same deminsions, but you all know what assume can do haha. Hope someone can help me out here, (also if this is in wrong spot, feel free to move it around mods) thanks:smiley_thumbs_up:
