I applied Woolwax inside the frame rails and, like so many Toyota truck owners before me, I snapped almost all of the plastic frame plugs that I removed.

I had a heck of a time trying to find part numbers for these plugs on the Lexus website, so I thought I might share this info with anyone else that might have had the same problem. I've owned Toyota trucks for nearly 30 years and finding Toyota part numbers has always been far harder than it should be. I'm still on the fence as to whether or not I actually need to replace the plugs, but I wanted to at least see how expensive they were.

All of my plugs had a label stamped on them, but I could find no relationship between this label and the actual part number.
Plug "A0" - 90950-01A50
Plug "4" - 90950-01987
Plug "7" - 90950-01991
Plug "H" - 90950-01A38
Plug "P" - 90950-01A39
Plug "X" - 90950-01A40

The images in this link are somewhat unique for these plastic plugs in that they show the friggin' part numbers in the diagrams.

I hope this helps someone!

Thanks for posting - this is a huge assist. I had no idea what frame plugs were - but have heard of applying woolwax - so this helps!
 
As a side note, some of these parts are shared with Toyota-branded vehicles on the same TNGA platform. Playing around with what appears to be the same retailer (not to call out any specific website, but for example, going to lexus.store.retailer.X rather than toyota.store.retailer.X), the same parts are 10-20% more on the Lexus side of the site. Since some of these plugs are only used on the GX, I had to purchase from the Lexus subdomain. Splitting my order didn't make sense since I would need to pay twice for shipping.

Not a big deal in this case, since these were only a couple bucks a piece, but something to keep in mind if I ever need a more expensive part - always check the Toyota store first!
