That's too bad. I can see why some might not want or need the rails if they don't provide any adjustment.
There's a limited range of where I might want to locate the cross bars but I like being able to fine tune the spread between them.
The holes on my cargo box were pre-drilled but I guess it is pretty easy to drill new holes to fit.
I bought OEM via Amazon for my 2019. One thing to note on install, make sure you install bolts vertical as it seems easy to cross thread. I also thought the 30 Torx head bolt was little shallow for the Torx bit so be careful if using a power driver.
OK, so my rails shipped without the (foam?) "Packing" strips that go between the hardware/risers and the factory-installed mounting locations. The seller can/will not ship. Can anyone describe the material or recommend a substitute? Are these strips absolutely necessary?
