Part number help, very obscure part

[straycat76]

Hello, I was wondering if you fine folks could help me locate a part number for me. I have searched so many times and have come up with nothing.

The attached photo shows a complete 3rd Gen roof rack assembly. What I need help with is the part number that is circled in red. They are the nuts that the screw-down bolts (circled in blue) screw into to secure the cross bars.

I am missing one. And since it's loose, every bump on the road I hit the loose crossbar will make an awful thud noise (this alone took me weeks to finally track down, too). I don't exactly know HOW I ended up losing one of these things, but it's definitely gone.

Can anyone help out? I recently ordered what I thought was the right part from toyotapart.com (Part No. 00278-00895 - HARDWARE KIT, RF RACK), but they only sent me the screw-down bolt...which isn't exactly what I would call a "kit".

Thanks guys!

I don't have the part number but a few thoughts.
1. I had several extra last year when I painted my rack. I bought an old rack from junkyard and it came with them. That may be easier - going to junkyard
2. I don't use the crossbars that lay flat. I took them off years ago and don't miss them
3. Those pieces are probably impossible to remove without taking off the end caps since they are in the rail. Have you looked around wherever you were when you pulled the caps. If your picture is accurate you are missing two not one. I think the end bars and the cross bars use the same piece so you will need eight total
4. Captain obvious here - but have you looked at the bottom of the cross rails to see if it is still screwed on. If you pull the end caps off you could theoretically slide the cross bars out with the piece attached

1. Ill have to go to a junkyard, agreed. However at this point its a principle thing haha. Why is it so difficult to find this part number?
2. I have had the crossbars off since discovering the missing nut...and kind of miss them. Without the crossbars, it looks less 4runner and more ordinary SUV.
3. That is why its so perplexing on how i could have lost one. I have never removed the crossbars, nor have i ever removed the end caps (all 4 are intact). The pic was swiped from ebay, so i didnt do an inventory hah, but looks like youre right...that setup missing one as well. IM not 100% thats a 3rd gen roof rack either.
4. I wish it were that easy...but yeah, i have it completely unassembled (except the rails).

Thanks for the response though. Im just going to have to find a local yard to find one of the stupid things.

There are other parts of the roof rack that they don't make anymore. Loof for thread for 1-2 weeks ago on this. There is a small rubber gasket that goes between the roof and the plastic backing of the rails. Those gaskets are no longer available. Several solutions are in the other thread
