Default Brake dust cover rusted

I thought I had gravel between rear disc rotor and dust cover in 2010 Rx .
But no, the dust cover has rusted.

What is the part number of the rear dust cover?
Do they exist as aftermarket part?

I can find all that for 2nd gen Rx but not for 3rd.
The part number should be in this diagram but it is not

I use Lexus of South Atlanta on line parts to establish the part number. You can also ask/confirm from your local Lexus parts dealer with your vin number. You should be under no obligation to purchase ti from them.

I would look through salvage yard offerings.

You could try Rock Auto dot com for aftermarket. I bet the Highlander and Venza take the same part.

Nothing in Rockauto which is surprising or I have just one of the first of these rusted out. And the vehicle won't pass yearly legal inspection if they are not intact.
It seems Dorman is common brand for aftermarket covers in Rockauto but they don't make this model yet.
I sent inquiry to local dealer and to Amayama with vin number, let's see what's coming

Although after looking at both your link and the one above from Lexus South Atlanta Parts, I do not see what I would consider a dust cover. I think of a dust cover as the thin metal shield over part of the caliper to keep dust off the wheel.

Hi!
At least in front wheel diagram the metal sheet behind rotor has named as dust cover. Not very describing name but that's the part I need. See attached image
And the weird thing is why the same part is not seem in rear in any diagram I have seen

They are expensive!
That link gives me a empty page in Ebay but with some fiddle it offered Gs model rear dust covers that pointed right direction for part number.
Rear disc dust covers are in parking cable category.

261.32 each on sale here for RX350 but I found about 108 usd each plus shipping with part number given for my vehicle Vin
It's still double the price of pair of aftermarket ones for 2nd gen.

Actually that usd was not mistake, I was meaning the currency US dollars, Amayama lists them 108USD each +shipping +custom.
But it will need all new brake parts too, rotors, pads, parking brake shoes. Those dust covers are attached under wheel bearing units so have to pop out drive shaft too.

As additional question
What kind of nut has the rear half shaft?
The same 16-corners 32mm hex nut as the 2nd gen model?

I do not know, but suspect it would be the same. Again the Lexus South Atlanta parts list or Rock Auto may be able to help.
