Installing 2015 Bed Extender in 2007

My father recently traded in his 2015 for a newer truck and gave me his OEM bed extender. It should work on my 2007, but I am unsure what parts I need to get. Has anyone done this? I know I will need some brackets, but I don't know if the 2015 brackets fit the 2007. I did not have a chance to look at his truck before he traded it, so I can't check to be sure. Also, the bed extender has a couple of small straps with buckles. I am unsure what these are for since I have never owned a bed extender before. Do I need additional parts to secure these buckles to the truck?

 

Not sure of part but I'm 100% it will work. It's the same bed

 

I've tracked down this part number:

$37 PT329-35051 Bed Extender Bracket Kit

PT329-35051.

Can anyone think of anything else I would need?

 

The straps are to connect the extender to the tailgate (they attach to the tailgate latches on each side). I guess it's to keep the extender from bouncing, but I never use them. All you need are the brackets that mount to the truck. I used some black marine caulk after drilling the holes for the brackets.

Make sure you test fit before drilling holes. Be sure your extender will flip and your tailgate will close properly

Edit.. those brackets don't look anything like mine... I have the

$310 PT392-35000 Bed Extender

PT392-35000 extender

 

In the end, these worked great:
