Can I add a SR5 2nd Row Seat Back in a Platinum?

Im missing the backs on my 2nd row seating, and I found them cheaper for the sr5 just wanted to know if they should still fit, from what the info says on the website it says without leather, so im guessing they are carpet back panels on the 2nd row seating in the SR5.

If someone who knows can confirm, also would i also need special hardware to attach them?

These are the panels I was looking at buying below.
Panel 1
Panel 2

Here is what my seats currently look like here
