If you aren't able to find anything, try browsing the local CL/OU/FB/KSL. The FR slimline II is very modular and often the same tray is used on several different vehicles. You can get the vehicle specific mounts and deflector separately from FR.
I ended up buying a used full size rack for a 5th gen 4runner, and used the tray on my 200 series with some rails and deflector I bought directly from FR. Sold the 4runner rails to someone making a custom rack.
