From what I saw online the items below are saying they only fit the 1500 Classic (DS) , not the 5th Gen(DT)
82212966 is the Management System, so 2 Horizontal Floors, 3 dividers, 2 nets. $166
The following are showing they fit the 5th Gen (DT)
The ones I found online were 82215793AB for $77 for 1 side. That is just the 3 dividers.
I didnt buy them, that was when I was looking.
