Has anyone used this patch panel

[-T-]

its listed as the outer 4" of cab floor with rocker channel and inner rocker. I need to replace just the section of floor right at the rocker panel. Just don't want to order this if its not what I need as GMC pauls doesn't do returns very easy. Most other retailers sale a 7" outer floor patch which is way more than I need.

Thanks for any input
