Rock rails from Land Cruiser first edition do not fit on my gx550 premium😵🤬

[Nebula'Nomad]

Hello everyone, I'm located in Orlando Florida and I've met up with another Forum member from the Land Cruiser forum, we met up yesterday and swapped out my roof rails and crossbars for his first edition Land Cruiser roof rack. Everything went smoothly with the roof rocks. Next we were swapping my OEM running boards for his Land Cruiser first edition Rock Rails. My running boards fit perfectly on his Land Cruiser but his OEM Rock Rails did not fit on my Lexus GX 550 premium the corresponding holes on the frame of my truck are there but they are not threaded so the 14 mm bolts used to attach the rock rails to the frame simply pop in the hole. The holes seem to be oversized versus what's needed to attach the rock rails to the frame of my Lexus. Has anyone else encountered this issue or is my truck a one-off defect from the factory? I've gone on Toyota's website as well as Lexus website and the part numbers for the driver and passenger side rock rails are identical. Am I missing something? Or does my Lexus require special Hardware?

I suggest you take it back to Lexus and have them confirm.

As of right now that is my plan. Trying to figure out if anyone else has had this issue or if I'm missing Hardware

Following for Lexus’s response but I would agree what I’ve understood is that Land Cruiser rock rails or even the OT rails do not fit the premium or lux

Well Lexus has confirmed that premium and luxury do not have the ability to have OEM rock rails installed as a simple bolt on. However the maintenance tech pulled me to the side and said that there is the ability to weld these directly to the frame and just like that The Rock rails will fit.
Not sure what i will do yet... not having any rock rails or running boards have grown on me

My wife has a Land Cruiser FE with rock rails. I have an Overtrail with running boards. Are they swappable?

Yes they are interchangeable if you have a overtrail

I'm in a similar boat. I have a Lux+ because we need a 3rd row and it was first available on the waiting list.

I'm still trying to make it as off-road capable as possible and just from the few mudholes I've dipped it in, those retractable running boards aren't gonna cut it . Did you find a solution to this? I just read your post tonight, so I haven't crawled under there to look yet, but is there any way to thread a nut/bolt arrangement on the backside of the holes? Some rock sliders would round out my "protection plan" for this dad-mobile/overlander.
