I spoke with my contact at WeatherTech and he said part # WT447091, which you referenced, includes the front driver's-side and front passenger's-side floor liners.
For custom fit cargo mats that fit from behind the third row seat to back of your 2015 Kia Sedona you will want part # WT40645. view full answer...
There are 2 different bolt sizes in the hardware for the Curt Trailer Hitch Receiver # C13340 which is a confirmed fit for your 2004 Kia Sedona. You will need 2 Hex Bolts that are 1/2-13 x 2" and 4 Hex Bolts that are M12 - 150 x 40 HEX.
You can actually order replacement hardware from us by ordering part # RHK on our website, choosing "Curt" from the drop-down manufacture selector, and then typing in your part "C13340" in the Hitch Item Number slot.
I have attached a video of this hitch... view full answer...
