Magnum rear racks on 2016?

Hello all,

I already have a Magnum sport rack on my 2016 Tundra and am now interested in getting the Magnum rear rack along with the 72" extension bar so that I can better carry two kayaks. Magnum lists the rear racks as only being compatible with 2017-2022 Tundras but I suspect that it'll fit on my 2016 fine as I don't think any changes were made to the bed area between 2016 and 2017 models. I'll probably contact their support to ask this but they'll obviously be closed at this time and I was hoping that someone here might have first hand hands-on experience with it. Can anyone confirm that the Magnum rear racks will fit on a 2016 or at least confirm that there weren't any changes to the truck bed between 2016-2017? Also, I was planning on getting the 20" rack version, do you think that would be the best size to go with my existing rack? Thanks.
