The tarp you need is the part # EX37645 since the part number for the FullTilt you'd have on your 2010 GMC Sierra 5-1/2 foot bed is the part # EX38645.

Thanks for the response, I thought I had typed in 6 foot 6 inch box though. Is the part number for that length EX5650?

You'd actually need the part # EX37650 instead since the tonneau you have is the part # EX38650.
